Mask of betrayal - Maureen O'Brien

By the time the woman's body is discovered in Kate Creech's bath it is beyond recognition - not surprising as Kate has been away on tour for seven weeks. Summoned back to London by Detective Inspector John Bright, Kate finds her home is a gruesome crime scene. She does not recognise the body, cannot guess why someone should have been using her house in her absence and has an unshakeable alibi. Perhaps she was the intended victim? John Bright suspects Kate is not being entirely open with the police and he is right. Kate has lent her keys far and wide and is fearful both victim and killer may be a part of her social circle. She goes on the run in an attempt to do her own detective work, but discovers Bright is always on her tail, even when she has gone down some very strange by-ways, discovering that it is not always clear who is the betrayer and who the betrayed.
