Another Man's Poison — Ann Cleeves

Ursula Ottway may have outlived her time, but she's still a tough old bird.

When she finds her beloved cats and some protected wildfowl dead of illegal poison, she angrily threatens to expose her landlord, politician Marcus Grenville, as an anti-preservationist.

Within hours, Ursula is dead, and Grenville, who is counting on his reputation as a committee environmentalist to boost him into Britain's cabinet, is greatly relieved -- until it's discovered that Ursula, too, has been poisoned.

As those quietly astute investigators George and Molly Palmer-Jones reconstruct the last days of Ursula's life, it becomes clear that her sharp eyes and long memory posed a deadly threat, not only to Marcus, but to his chilly wife, his alienated offspring, and others. To bring a killer to justice, Molly and George must uproot a lifetime's worth of secrets and expose a nest of vicious human vultures.
