Double-Crossed

When the Slisher Detective Agency--which includes thirteen-year-old Niki, her two sisters and parents--receives a call to help find a missing man, the family immediately jumps into action. Solving crime is their specialty, after all. And if they find the man, perhaps they'll also retrieve a valuable ancient cross he supposedly stole. But the family of five didn't count on Niki's kidnapping or some of the other unexpected twists during their search. Will this be the agency's first failure in capturing the criminal? This mystery, a tale of a family working together, is full of action, fun facts, and a surprise ending.
