The Chocolate Mouse Trap (Chocoholic Mystery Series #5)

Chocolate-shop manager Lee McKinney has had enough of party planner Julie Singletree's cutesy e-mails. Then somebody actually kills the woman, putting everyone on her mailing list on edge.  As their connections to the murder emerge, so do more attacks. Lee smells a rat-and it's not made of chocolate. And if she doesn't want to be permanently deleted, it's up to her to trap it.
