Inspired by the magnificent Bodysnatchers (another Dr Who title from Mark Morris), I thought I'd read this, his second contribution to the series. As in Bodysnatchers, here he revels in the ability to concoct the most stomach churningly disgusting scenarios, happy in the knowledge that it never has to be made. The joys of writing over filming, perhaps. And there's PLENTY of blood and guts to worry about. Limbs fly, huge spider things (Xaranti I think they're called) clamber around ripping people apart... the book STARTS with somebody dying messily on a boat. Natured the Doctor and chums turn up, get involved (with ex UNIT guy Mike, before or after his transition to becoming a Monk, I'm not sure...) and Tegan meets a guy. This guy dies... messily of course... along with a huge portion of the population of the town they're in. It gets to quite chaotically messy levels, and yet ends in a limp, painfully half-arsed way. Yes, the Doctor asks the alien leader to leave. And the aliens leave, presto. Memories are erased, and everything's peachy. Er, did I miss something? Hundreds are dead, blood's everywhere, and he just ASKS them to go away? It's such a huge cop-out after a moderately impressive gore-fest. Still, the book is enjoyable for the most part: "There's a monster on the beach, sir!" This would have been an impressively adult TV episode, were it not rounded off with such a lame resolution.
