Murder strikes close to home when an altercation between two dog owners in the famous Parc Monceau triggers a brutal murder in an alley behind the Paris apartment building of expat and private eye Claire Baskerville. Already struggling with the unexpected and rancorous visit of her daughter Catherine—as well as the desperate hunt for one of her missing grandbabies—Claire is reluctant to take the case of the murder of Madame Lavigne until she is brutally shown how vital it is that the elderly dog lover gets justice. Not just for her, and the building they all live in, but for Claire too—and as it turns out, the safety of her whole family.
