Maisie Dobbs Mystery - book 2

No sooner has Maisie discovered the identities of three of these friends than they start turning up dead—poisoned, then bayoneted for good measure. At each crime scene is left a white feather. Increasingly preoccupied with these tragedies, Maisie almost loses sight of her original mission, until it becomes apparent that the murders and Charlotte's disappearance are related.
What I enjoy about this series is the layers in the storyline. Maisie's assistance, Billy Beale, has been struggling with chronic pain from a war wound. But lately even Maisie has noticed an erratic change in behavior and discovers that he has been self-medicating using cocaine. So she strives to find a way to help him that doesn't destroy their relationship. I find her storytelling really compelling and am looking forward to reading the next book.
