Murder by Martini With a Twist

Murder by Martini with a Twist is a time-travel mystery story. Caldwell suddenly finds himself walking across a parking lot to climb a stairway that runs 500 feet up the back of a tall building. He passed through a doorway; as he descends, he runs out of stairs and luckily lands on a soft, fluffy mattress in the Bedding Department in a unique indoor mall built in the 1950s. He runs into his young grandfather, who solicits his aid to solve the murder of Caldwell's grandmother.
