In 1860 Scotland Yard's 'Prince of Sleuths' Jack Whicher is sent to rural Wiltshire to investigate the murder of three-year-old Saville Kent,snatched from his bed at night and killed.Saville's nurse Elizabeth Gough is a prime suspect but released for want of evidence though local Superintendant Foley is convinced it is an inside job. Foley gives his help grudgingly,disdainful of 'modern' methods,speculating that Saville woke to see Elizabeth with a lover,possibly Saville's father,an unpopular man. Part of a woman's torn garment is found,stained in blood,and Constance,Kent's sixteen-year-old daughter from his first marriage, claims she lost a night-gown. Dr. Stapleton,the family physician,tells Whicher that Constance,like her mother,is dangerously unstable and jealous of Saville. Both she and younger brother William hate their stepmother Mary,their former nanny,with whom Kent cuckolded their mother...

Poppy Cross is happy-go-lucky. At 30, she lives in Camden: cheeky, playful, frank while funny, and talkative to strangers. She's a conscientious and exuberant primary-school teacher, flatmates with Zoe, her long-time friend; she's close to one sister, and not so close to another. In this slice of life story, we watch her take driving lessons from Scott, a dour and tightly-wound instructor, take classes in flamenco dance from a fiery Spaniard, encounter a tramp in the night, and sort out a student's aggressive behavior with a social worker's help. Along the way, we wonder if her open attitude puts her at risk of misunderstanding or worse. What is the root of happiness?
