A piercing scream brings Superintendent Adam Dalgliesh hurrying from his literary party to the Steen Psychiatric Clinic, where he discovers the body of a woman and a chisel thrust through her heart. As he probes beneath the unruffled calm of the clinic, he discovers that many an intrigue lies hidden behind the Georgian terrace's unassuming facade.

Mildred Lathbury is one of those 'excellent women' who is often taken for granted. She is a godsend, 'capable of dealing with most of the stock situations of life - birth, marriage, death, the successful jumble sales, the garden fete spoilt by bad weather'.

The proposals of The Peverell Press's ambitious new managing director, Gerard Etienne, have made him dangerous enemies. When Gerard's body is discovered bizarrely desecrated, there is no shortage of suspects and Dalgliesh and his team are confronted with a puzzle of extraordinary complexity and a murderer who is prepared to strike again.
