CAUGHT. Harlan Coben/Orion, £7.99.

REPORTER Wendy Tynes fronts a TV programme that tracks down and brings paedophiles to justice.

Dan Mercer, a youth worker who helps disadvantaged youngsters, is her latest target. But crucial evidence is ruled inadmissible and Mercer walks free and Wendy loses her job. Blaming herself for the collapse of the trial, she mounts a further investigation on her own and is surprised to get a call from Mercer claiming he was set up and asking for a meeting. The case becomes a murder hunt and suddenly Mercer is also connected with a missing 17-year-old girl. But as Wendy begins to piece together a jigsaw of information, she herself becomes a victim and discovers the dark powers of the internet.

A brilliant and complex thriller from a master of his craft that is full of well drawn characters, has a pulsing narrative and unexpected twists to the final page.
