Despite his classic work in the 70's on Doctor Who, Barry Letts doesn't have good form for his more recent work, and continuity-wise Island of Death slots in after the much maligned radio dramas The Paradise of Death and the Ghosts of N-Space. The plot is very generic, with a corpse on Hampstead Heath leading the 3rd Doctor, Sarah Jane Smith and the Brigadier off to combat a group of new age cultists who are summoning an invasion force of parasitic aliens. The novel grinds to a halt during an interminable 100-page sea journey as the regulars give chase to the cultists, and the supporting characters are either caricatures or distinguishable only by name. When events finally get to the island the alien Skang are reasonably interesting thanks to their `perception is reality' hypnotic powers, and Letts keeps enough moments of light humour with the regulars going (including the Doctor literally talking to fishes) that the novel is at least readable. By no means a good novel, Island of Death is at least an improvement on Letts segment of the Deadly Reunion novel written with Terrance Dicks.
