Rabbits Out of Hats — A.L. Kessler

Lacey Willow isn't just a witch. She's a bad one. Any attempt to use magic tends to end in quirky ways which is why she owns a magic shop where people purchase amusing parlor tricks. When her new shop neighbor turns out to be a PI, Lacy is unprepared for the shenanigans that are about to go down. Soon she finds herself accused of stalking, snooping around a funeral parlor, and dealing with hexes while she tries to clear her name.
