B20 - Watching The Dark

When Detective Inspector Bill Reid is found murdered in the tranquil
grounds of the St Peter's Police Treatment Centre, and compromising
photographs are discovered in his room, DCI Banks is called in to
investigate.
It emerges that Reid's murder may be linked to the
disappearance of an English girl in Tallinn, Estonia, six years earlier.
While DI Annie Cabbot looks into the case in Eastvale, Banks travels to
Tallinn to track down leads in the dark, cobbled alleys of the city's
Old Town. But it soon becomes clear that someone doesn't want the past
stirred up, and that solving the interlinked crimes may put even more
lives in jeopardy.
