We’re back, with another Big Finish Doctor Who audio drama review! This week, we’re listening to The Oseidon Adventure, the conclusion to the Fourth Doctor Adventures, series one. Let’s get started!
Spoilers ahead for anyone who has not listened to this audio drama!
Immediately following the events of Trail of the White Worm, the Doctor and Leela watch as the white worm transforms into a spatial wormhole, and the Master calls his allies through. Many tanks come through the wormhole, until the Master stops the rain, causing the procession to stop. The tanks are occupied by Kraals of the Second Kraal Army—and they are led by Marshal Grinmal, who remembers how the Doctor destroyed the first army. The Master offers the Doctor as a gift to the Kraals, who summon their deadly android servants. The Doctor sends Leela away as the Androids take him down; she promises to return with allies and weapons. The Master sends Spindleton in his own tank to recapture her. Grinmal wants to take the Doctor back to their homeworld of Oseidon, but the Master wants to kill him now; the androids intervene and disarm the Master, taking away his staser; they then send the Doctor back through the wormhole to their chief scientist, Tyngworg. Meanwhile, Spindleton loses Leela in the woods, and sends his helicopter to find her. The Kraals bring the Master back to the house with Spindleton. Grinmal negotiates with Spindleton, who wants to rule England when the Kraals conquer the rest of the world; Grinmal approves the plan, and imprisons the Master in the stables; he swears revenge.
Leela uses a horse from the stables to trample the androids guarding the Master. He tries to hypnotize her, but she slaps him, breaking the spell; she frees him, intending to make him fly the TARDIS to rescue the Doctor. Meanwhile, Spindleton and Grinmal confer about strategy, and Spindleton wants them to attack the local village, Dark Peak, as an example to the surrounding country. Spindleton wants to burn it, but Grinmal suggests a matter-dissolving bomb. On Oseidon, the Doctor is restrained by Tyngworg; he jokes about having been strapped to that table before. Tyngworg intends to drain off the Doctor’s knowledge with an analyzer device, as his predecessor once tried to do; it will take eight minutes. Outside Spindleton’s house, Spindleton and Grinmal see Leela and the Master race by on one of Spindleton’s prize horses; Spindleton prevents Grinmal from shooting them, for fear of hurting the horse, assuming that the army will hem them in. Grinmal dispatches the army toward Dark Peak. Leela gets the Master to the TARDIS, but the Kraals are guarding it; therefore Leela takes Master and the horse through the wormhole to Oseidon. Beholding the ruined landscape, the Master explains that the surface is radioactive; he suggests that the Doctor is in the nearest of the Kraals’ underground bunker. Unknown to them, Tyngworg is monitoring the area, and overhears the plan.
The Master and Leela find the Doctor, who is disoriented and calls Leela “Tilly”; he explains about the transfer (or rather, copy) of his knowledge. Tyngworg is monitoring the cell as well, and hears the Doctor tell Leela that the Master will be dropping in on Tyngworg, and that therefore they should go there as well. Moments later, the Master arrives, but Tyngworg is on his side; Tyngworg mentions that the Doctor in the cell is an android duplicate, which does not know it is a duplicate. Tyngworg insists he is aware of events on Earth. The Master tries to hypnotize him, but is unsuccessful, and finds that he himself is an android; Tyngworg is the real Master in disguise. He sheds the disguise and destroys the duplicate. The real Doctor is still on the table; he congratulates the Master on his success; however, the Master still intends to kill him. First, however, he resumes Tyngworg’s voice and calls Grinmal for an update; Grinmal reports that Spindleton has delivered a slightly-eccentric ultimatum to the British government. He also reveals that UNIT is approaching, and the Master orders him to detonate the bomb as soon as UNIT arrives, even if the ultimatum has not been answered. When Grinmal objects, he activates an override code for the androids, ordering them to return to Dark Peak and activate the bomb. The Doctor congratulates him again, but then says it may have been a mistake to leave him connected to the analyzer; his ongoing experiences are still being fed to the android duplicate, so that it knows everything now. The android arrives to attack, but is shot down at once; but the Doctor is not deterred. Instead, his duplicate had taken the opportunity to create a Tyngworg duplicate, which is even now ordering the androids to disarm the bomb and attack the Kraals. The Master loses contact with Grinmal, but in retaliation, he orders an autodestruct of the android Tyngworg. He then moves to attack the Doctor, but suddenly funds that again, he is an android—and as he ceases to function, the real Master has yet to be seen. Leela rejoins the real Doctor at the behest of the duplicate—and the Doctor wonders where the real Master is, and what he is doing, as the Kraal invasion seems to be a distraction.
On Earth, UNIT is mopping up the Kraals and the androids, but they can’t find Spindleton, and astrange-colored blood trail leads into the woods. The duty officer at UNIT HQ hands the base over to the Master, and is killed for his trouble. Spindleton and the Master infiltrate the Doctor’s old lab at UNIT, where Spindleton begins to rebel; however, the Master hypnotizes him and sends him out to join the guards. On Oseidon, the Doctor and Leela create a new duplicate of the Master to interrogate. The duplicate doesn’t believe he is an android, so the Doctor has him try (and fail) to hypnotize Leela; he lacks the psychic empathy field that real Time Lords possess, and therefore cannot do it. Leela intends to melt him down, causing him to beg them to stop; the Doctor wants him to betray his original self, but he refuses. The Doctor realizes that the wormhole is an integral part of the Master’s plan, but how? He realizes the duplicates have the Master’s personality, but not his knowledge relevant to the current situation; therefore he looks at recently-deleted items in the Kraal computer. He finds a file indicating that two types of harmless radiation, Z-radiation and O-radiation, can combine to create deadly ZO-radiation, which has the power of a billion neutron stars. The Master duplicate realizes that the real Master wants this radiation to restart his regeneration cycle and become functionally immortal. If he does so inside the wormhole, he will survive the process. Oseidon is saturated with O-radiation; for the requisite Z-radiation, he turned to Earth, knowing that the Third Doctor once stashed a Z-radiation battery in UNIT HQ after failing to jump-start the TARDIS with it. The android breaks free of its restraints, forcing the Doctor and Leela to run away. The duplicate accesses the records to learn the real Master’s plan; but he finds a message from the real Master, who anticipated this possibility. Accessing the deleted files activated a matter dissolution bomb under the lab, which will detonate in seconds.
Outside, Leela recovers the horse, and uses it to get them back through the wormhole to Earth. There they meet Captain Clarke, who is acting commander of UNIT while the Brigadier is away on business in Canada; the Doctor has him contact HQ, but he gets no response. The Doctor realizes the Master must already be there, trying to steal the battery. The Doctor persuades Clarke to order the convoy back to HQ; he takes Leela to recover the TARDIS and get there ahead of the soldiers. He insists that if the Master has already succeeded, Clarke will meet him on the way back to the wormhole; the battery plays havoc with TARDIS navigation systems, forcing the Master to transport it by road. At the TARDIS, they encounter Grinmal, who alone survived the betrayal. Leela subdues him. However, the Doctor hears a helicopter, and realizes that the Master is sending the battery through the wormhole in that manner. As anyone aboard will die in the detonation, the Master can’t be there; and they only have until he arrives to recover the battery and seal the wormhole. Grinmal realizes his world is about to be destroyed, and volunteers to help stop the Master; he takes Leela and goes to recover the battery, while the Doctor wants to find out how to seal the wormhole. Meanwhile, Spindleton has arrived on Oseidon with one of his men and the battery; they set up in the mock village of Devesham that the Kraals use as a training center.
Using the TARDIS, the Doctor intercepts the Master, who admits to the plan. The Doctor tricks him into admitting that a temporal pulse will close the wormhole, as executable by any TARDIS. However, the Doctor reveals that the ZO radiation cannot be controlled; he suggests that this Master as well is a duplicate, and that the real Master is waiting in orbit. The Master draws a staser, and decides to kill the Doctor at once. On Oseidon, Leela and Grinmal kill Spindleton’s man, and intends to recover the battery, but Spindleton reveals that it is very unstable, and will trigger if he falls on it. He reveals his goal in the plan; the Master promised him a rebuilt country, filled with android duplicates which will obey him. Spindleton shoots Grinmal.
The Doctor demands proof that this Master is genuine before he dies; he suggests that the real Master intentionally withheld knowledge about the uncontrollable nature of the radiation. The Master insists he is real because he can sense a Time Lord in the vicinity (a function of the psychic empathy field), whereas the Doctor doesn’t sense one. The Doctor admits defeat. The Master contacts Spindleton and reasserts his control over him; Leela sees this and attacks Spindleton, dragging him away from the battery. The Master tells the Doctor he will activate the battery by remote; and he forces the Doctor toward the wormhole. However, the android from the exploding lab comes through the wormhole, having escaped the blast with only some damage; the real Master fires on him, but staser blasts can’t hurt an android, and the duplicate captures him, leaving the remote with the Doctor. The duplicate drags the real Master into his TARDIS, intending to force him to repair him and give him control of the TARDIS, as he now considers his android self to be the superior version of the Master. The Doctor bids them goodbye, and takes his own TARDIS to Oseidon’s Devesham. He finds Leela and Spindleton, and plans to take Spindleton to UNIT custody; but Spindleton intends to stay here, finding this mock village preferable to the real England. He sends them away, but asks them to take the horse home and set it free; though it’s a magnificent horse, history reports that it was a famous stolen horse, and therefore they can’t return it to its original owners. They depart in the TARDIS with the horse.
After a rocky start, the first series of Fourth Doctor Adventures ends strong in this story. We pick up immediately after the events of the previous entry, Trail of the White Worm, with the titular worm having transformed into a wormhole to the planet Oseidon, home of the mutated and militaristic Kraals. In typical Master fashion, what follows is a series of twists. The Kraals are known for one thing in particular; they create fantastic android duplicates which have not only the form of their victims, but also the personality. Therefore, once this story begins, it will be a long time before you know who is real and who isn’t. I won’t spoil it; but for once the twists are perfectly deployed. Once again we see the mock village of Devesham as deployed in The Android Invasion; and this time it ends up with a permanent human resident at the end (although, if he is not also an android, he may not last very long—a point that isn’t really addressed when the Doctor leaves him there).
This is a UNIT story, and as such it is hard to get a firm date. The promotional material indicates it takes place in 1979, but with the difficulty in dating UNIT stories near the end of the Brigadier’s tenure (due to contradictory statements within the classic series—the infamous “UNIT dating controversy”), it may actually have to be as early as 1975. UNIT HQ is mostly unchanged, with the Doctor’s things still in the lab. The Brigadier is still around, but is not seen here, being on assignment in Canada. The Master seen here is again the Geoffrey Beevers incarnation as seen up to The Keeper of Traken, indicating this story predates that serial, but comes after Dust Breeding. He’s at his best here, playing several conflicting versions of himself; with disguises and stasers and plots within plots, this is a story that harks back to the Master stories of the Fourth Doctor era very well, and even somewhat to the Third Doctor era.
Leela gets a better treatment here than in some of the earlier stories. I don’t mean to harp on the same point all the time, regarding the Doctor’s poor treatment of her; it’s just that it continues to be relevant! Here, however, there’s none of that for once (she does get called “Savage”, but by the Master this time, and his opinion hardly counts). She’s quite a force in this story: rescuing the Master, navigating the wormhole, freeing the Doctor, taking out the Kraal leader Grinmal, and then allying with Grinmal to recover the Z-battery, the story’s macguffin. She began the series weakly, but ends very strong, and I couldn’t approve more.
There’s one new bit of technobabble here, which adds to the lore of the series a bit: Time Lords possess a psychic empathy field, by which they recognize each other when close together, and by which the Master is able to easily mesmerize others. It’s been handwaved a bit in the past, but here it’s an integral part of the story.
References are mostly back to The Android Invasion, and I’ve covered most of them. The Doctor does refer to meeting the Master last on Gallifrey (The Deadly Assassin); and the Master’s TARDIS is in the form of a grandfather clock, which it will still be as of The Keeper of Traken.
Overall: Great story, with little to complain about. If Series Two is this good, we have something to look forward to.
Next time: I’m debating between Series Two, with the Fourth Doctor and Romana I (played by Mary Tamm before her untimely death), and another range. We’ll find out next week. See you there!
