Simon Serrailler is faced with that most complicated of investigations - a cold case. Freak weather and flash floods all over southern England. Half of Lafferton is afloat. A landslip on the Moor has closed the bypass and, as the rain slowly drains away, a shallow grave - and a skeleton - are exposed. It doesn't take long to identify the remains as those of the missing teenager, Harriet Lowther, last seen carrying a tennis racket while waiting for a bus. But that was 16 years ago.
How long will it take to trawl through the old, stale evidence and assess it anew?
