These two Anne Perry novels feature the Monk family – William, his wife Hester, adopted son Scuff, and street urchin Worm – all working together to solve the current crime.
In Blood on the Water, Commander William Monk of the River Police is on patrol when the Princess Mary explodes, sending nearly 200 passengers to their death. Soon after Monk begins his investigation, the case is transferred to the Metropolitan Police due to its “international implications.” But Monk and his family cannot leave the case alone: Hester attends the trial of the captured suspect, son Scuff (who spent his young years on the waterfront as an orphan) questions waterfront denizens like Worm to get first-hand information, and Monk continues to follow the case. After a rapid trial and conviction, Monk raises questions of guilt and the river police is reassigned the case. Motive, access, and high level involvement are unclear as the Monk family pursues the truth.
In Corridors of the Night, Nurse Hester Monk becomes the protector of two small children who are being used to supply blood to a very ill man undergoing an experimental treatment. The scientist conducting the treatment has little regard for the children or Hester such that Monk and Scuff need to rescue her from what is a near kidnapping.
