A missing person sets off the action in this classic whodunit from the bestselling mystery writer known as the American Agatha Christie.   In The Window at the White Cat, bumbling lawyer Jack Knox agrees to help a beautiful young woman find her missing father. But when the politician is found dead at a backstreet social club serving up beers and illegal favors, and Jack’s aunt disappears, it looks like the daughter’s fiancé may be guilty of more than winning her heart.   A #1 New York Times–bestselling author with ten million books in print, Mary Roberts Rinehart crafted a career out of writing mysteries that set the stage for generations of writers to come.   “[Rinehart’s] literary distinction lies in the combination of love, humor and murder that she wove into her tales. . . . She helped the mystery story grow up.”—The New York Times
