Prominent GP Arnold Pettifer is found dead of an overdose, alone in his house and with a note by his side. All the evidence points to suicide, but Inspector Luke Thanet is immediately suspicious.

The finger of suspicion points at Mrs Pettifer, particularly when it emerges that she has a lover. But Inspector Thanet suspects there is more to this case than meets the eye.
