An unabridged reading of this classic novelisation of a Seventh Doctor TV serial starring Sylvester McCoy.
The Doctor brings Ace home to Perivale - but on a summer Sunday it seems the least lively place in the universe.
All the members of Ace's old gang have gone away - each one disappeared.
What is killing the domestic pets of Perivale? Who are the horsemen whose hoofprints scar the recreation ground?
Where have the missing persons been taken? Is the Doctor stepping into a well-prepared trap - and if so, can it be the work of the Doctor's old adversary, the Master?
