In the 12th book of the Capital Mysteries—an early reader chapter book mystery series featuring fun facts and famous sites from Washington, D.C.—a legend says that on a dead President's birthday, his ghost haunts the famous retreat, Camp David. KC and Marshall are going there on October 14, President Eisenhower's birthday. They aren't worried until strange things start happening. How did a bat get trapped in their cabin? Why is there blood-red dirt in the trunk by the couch? And what is making the weird thumping noise? It's not Eisenhower's ghost...is it?
