After author Esme Carling is found floating in the Thames, Dalgleish re-questions the woman's 11 year-old neighbor who admits Esme wasn't home the night Gerard Etienne was killed. Others who may have had reason to want him dead have equally shaky alibis. DI Miskin looks into those and one in particular does not stand up to scrutiny. Another murder eliminates that person as a suspect. DI Daniel Aron finds a photo that links one of the Peverell Press employees to family dearths in Nazi concentrate camps in World War II. In the end, the killer does not obtain the satisfaction hoped for. A lapse of judgment on DI Aron's part leads to another ghastly death.
