A young woman investigates the death of her wealthy, estranged father in a small Rhode Island town in this novel by the author of the Peter Shandy Mysteries.

Murder can happen anywhere, even in sleepy Meldrum, Rhode Island. And while the town’s old-money families may prefer to sweep such unseemliness under their Oriental rugs, its newest resident can think of nothing else. Nineteen-year-old Jenny Cirak has moved into the house her father, a once-famous movie producer, willed to her. She’s also using an assumed name, just like he did when he lived—and died—in Meldrum. But why did he leave a fortune to the child he abandoned . . . and what really killed him?

Hoping to make sense of the father she never knew, Jenny must get to know his neighbors and expose their secrets and feuds. Somewhere among this cast of characters, which includes a retired corporate accountant from Baltimore who shows up on her doorstep with a clue, is a person who knows the truth—and will do anything to keep Cirak’s daughter from uncovering it.

In eleven stories, the brilliant sleuth tangles with a book thief, an assassin who targets acrobats, and more . . .

For Ellery Queen, there is no puzzle that reason cannot solve. In his time, he has faced down killers, thugs, and thieves, protected only by the might of his brain—and the odd bit of timely intervention by his father, a burly New York police inspector. But when a university professor asks Queen to teach a class, the detective finds there are people whom reason cannot touch: college students. Queen’s adventure on campus is only the first of this incomparable collection of short mysteries. In these pages, he tangles with a violent book thief, an assassin who targets acrobats, and New York’s only cleanly shaven bearded lady. Criminals everywhere fear him, whether they work in mansions or back alleys. No mystery is too difficult for the man with the golden brain.

The place: A European center of power in the emerging new world order.

The event: An international conference plotting the strategy for evangelism in the post-Cold War era.

Jackson Maxwell, Christian journalist, travels to Berlin intent upon capturing the spirit of this historic gathering. But behind the scenes, a much more crucial chain of events is about to take shape.
