Green Thumb — Ralph M. McInerny

One early morning during spring break, Detectives Phil Knight and Jimmie Stewart are enjoying a golf game at the University of Notre Dame when they find a man apparently suffering a heart attack on the green. They summon help and the man is rushed to the emergency room. But it's too late--the man dies at the hospital and an autopsy suggests that his death was not an accident.

The victim--poisoned with deadly nightshade--turns out to be Mortimer Sadler, something of a boor but also an extremely generous donor to the university. He'd returned to campus for an unofficial class reunion, along with several classmates, including his three college roommates. Soon, long-buried animosities surface among the old friends. But are these old wounds strong enough to result in murder? Or was there a more recent disagreement brewing? Phil and his brother Professor Roger Knight team up to uncover the truth behind Sadler's death.

Green Thumb is an intriguing addition to this series by the author of the beloved Father Dowling mysteries. Filled with suspense and plot twists galore, not to mention McInerny's trademark clever wit, it's guaranteed to enchant new readers as well as dedicated fans.
