XO (Kathryn Dance #3) by Jeffery Deaver

HE IS HER BIGGEST FAN.
AND HER GREATEST THREAT . . .

To its singer, 'Your Shadow' is just her latest hit.

To her obsessive fan, it holds a hidden message, meant only for him.

The night Kayleigh Towne gets an anonymous phone call, playing the first verse of the song, one of her crew -- an ex-lover -- is murdered, in a terrible echo of 'Your Shadow's' lyrics.

Off duty, and in town for the concert, Kathryn Dance is drawn in to the attempt to find the killer. As an expert in body language and behaviour, she knows that stalking crimes are never just one-time occurrences.

And the the second messages comes . . .
