"A Shaw & Valentime mystery"--Cover.

"One hot August day in 1994, 75 holidaymakers are ferried to an uninhabited island off the North Norfolk coast. Only 74 return alive. A young man has been stabbed and left to bleed to death in the island's surf. The case is never solved. Twenty years later, the new chief constable decides the murder is ripe for a re-evaluation using state-of-the-art forensics. DI Peter Shaw is in charge of the case and summons all 75 original suspects to a mass DNA screening. But one of them is unable to attend. Beautiful Marianne Osbourne is found dead in her bed, a wartime cyanide pill lodged in her throat. Is there a link to the 1994 murder?"--Jacket.
