May 1975. 8-year-old Darren and churchwarden Miss Wharton find two dead bodies in the vestry of St Matthew’s Church, Paddington, their throats slashed. One is Sir Paul Berowne, a baronet and recently-resigned Tory MP; the other a homeless man called Harry Mack. Dalgliesh is called in to investigate, accompanied by DS Masterson and his new DS Kate Miskin.

After the attack on Father Barnes while Halliwell was in custody, Dalgliesh brings Swayne and Lampart in for questioning. He discovers Lampart is having an affair with Lady Barbara, who reveals she is pregnant and thinks she will inherit everything. However, Lady Lavinia reveals that Sir Paul secretly changed his will at the last minute.
