The new Companion Chronicle audio from Big Finish takes its title and a bit of its setting from Tom Godwin’s famous short story. Here we have First Doctor companions Steven Taylor, played by Peter Purves, and 1960s City trader Oliver Harper, played by Tom Allan, stuck in a piece of space junk as the air runs out. The point of the story is the two-hander between the two principal characters which takes up most of the second half, a very effective bit of character exploration; I got a bit impatient with the slowness of the first half moving the story to get there, but perhaps some of this will turn out to be a setup for the next (and I suppose last) of this sequence.
