The Doctor brings Ace home to Perivale. On a summer Sunday it seems the least lively place in the universe, yet mystery lurks behind the calm facade. The members of Ace's old gang have gone away, each disappeared without trace. Something is killing the domestic pets of Perivale, and unearthly hoofprints scar the baked earth of the recreation ground. What strange force connects all these events? As Ace herself is transported to a distant planet, it seems that the Doctor may be stepping into a well-prepared trap. Can it be the work of the his old adversary, the Master—and if so, to what end? Lisa Bowerman, who played Karra in the 1989 BBC TV serial, reads Rona Munro’s complete and unabridged novelization, first published by Target Books in 1990.
