Magician Max Mephisto, now divorced and living in London, is on his way to visit daughter Ruby and her new-born baby when he is hailed by a voice from the past, fellow performer Ted English, aka the Great Deceiver. Ted's assistant, Cherry, has been found dead in her Brighton boarding house and he's convinced that he'll be accused of her murder. Max agrees to talk to his friend, Superintendent Edgar Stephens, who is investigating the case. What Max doesn't know is that the girl's family have hired private detective duo Emma Holmes (aka Mrs Stephens) and Sam Collins to do some digging of their own.
