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.
