Question of Identity [EPUB ebook] 

Lafferton is struggling through a bitter winter, with heavy snowfalls paralysing the town, though at least the police can be sure the ram raiders who have been targeting antique and jewellers’ shops will be lying low.The biggest worry the elderly have is how to keep warm, until 82-year-old Doris Upcott is found strangled in her home, followed by the deaths of 2 other residents of the same sheltered housing complex. Each time, the murderer has left a unique signature at the crime scene, which should help DCS Simon Serrailler, desperate to identify him before he kills again.When links are found between these and 3 similar murders elsewhere, Serrailler is obliged to cross unfamiliar territory in his search for answers.
