In the long, hot summer of 1969, two young men are involved in the accidental killing of their foreman on a Shropshire building site. Traumatized, they conceal his body and vow to never mention the horrific incident again. Four decades later, DI Frank Kavanagh and DC Jane Salt’s relationship is in trouble and she, desperate to avoid the cloying atmosphere that envelopes them in London, escapes to a friend’s home in that same Shropshire town. Here, whilst trying to avoid her own relationship problems, Salt gets herself embroiled in her friend’s love life and finds herself in serious danger. Can Kavanagh help her? Will their relationship survive this ordeal? And, vitally, can they now help solve a 40-year-old murder mystery?
