There's cash missing from a local charity thrift shop—lots of it. And when it looks like her surrogate grandma might be accused, there's nothing for Charlie to do but take a job there and try to catch the thief from the inside and clear Elsa's name. As she and Elsa begin tracking the missing money, it becomes obvious that the shop is a little goldmine and there are a number of people who could easily be after the money. She's narrowing down the suspects, but when the person who is tops on her list suddenly and mysteriously dies, well it looks like there's a lot more going on in the little shop than anyone ever guessed. Now Charlie has to face down both a thief and a killer.
