An uninvited guest. A missing identity. A trail of deadly secrets.

When a horrified bridesmaid finds the body of a young woman at a wedding reception, it makes the bride and groom’s choice of a Saints and Sinners theme all the more macabre.

There are no means of identification and nobody knows the victim.

The bride is convinced someone is trying to sabotage her big day. The groom is sure it’s a dreadful mistake.

It’s up to brilliant psychologist Alex Delaware and LAPD Lieutenant Milo Sturgis to uncover the truth. They have a hundred guests to question, and a strong suspicion that the motive for murder is personal…

The party’s over.

And the hunt for the killer is on.
