The authors of this Eighth Doctor novel, when on form, are among the best writers of the Who range. Unfortunately I was underwhelmed by this joint exercise of their talents, in which they attempt to jointly channel Agatha Christie, Mary Shelley, Marc Platt and a little H.P. Lovecraft, and the result doesn’t quite take off. Having two viewpoint characters who don’t quite know who the Doctor, Fitz and Compassion are is rather brave, but unfortunately I found them a bit interchangeable and at times implausible.
