Something Old, Something New, Something Foretold, Corpse So Blue

Psychic P.I. Piper Ashwell is hearing bells, and not just because she's getting married to her partner, Detective Mitchell Brennan. Piper's having visions of a murder at her own wedding. Mitchell is convinced she's getting cold feet, and it's messing with her abilities. But when a missing persons case turns up, and the victim is a little too much like the man she saw in her vision, Piper is convinced this is a case only she can solve. But can she prevent a murder and say "I do" at the same time?
