Crime rates in Lafferton do not conform to the national average. A serial killer has already been let loose on its sleepy streets. Now a young boy has disappeared. We, as readers, know that he has been abducted, snatched from outside his home while waiting for the school run. DCI Serrailler has only his wits and his sidekick, Sgt Coates, to deduce where the boy might be found.

Meanwhile, Andy Gunton has just been released from prison after serving a sentence for manslaughter (a petty robbery went wrong and Andy pushed his victim too hard). Will he find work and settle down, or be drawn back into the underworld by the sleazy, leather-jacketed, BMW-driving Lee Carter?

The great advantage of crime novels, suggested Allan Massie in that profile of Rankin, is that they can deal ‘more convincingly’ with ‘different levels of society’. Susan Hill segues effortlessly between the Dulcie estate where Andy was brought up, ‘down at heel and deserted in the rain’; the posh houses on Sorrel Drive, home to the snatched child; the tension of Serrailler’s incident room as he and his team desperately search for a lead, any lead, that might take them to the lost boy; and the cosy farmhouse life of Serrailler’s sister, Cat: ‘the hugger-mugger of a porch, full of Wellington boots and milk bottles … the warmth and tumble of his nephew and niece and the cat on the old sofa beside the Aga’.

She captures sinister atmosphere brilliantly (the stage adaptation of her ghost story, The Woman in Black, has been running in the West End for 15 years), whether it be the deserted airfield at 3 am, where Lee Carter carries on his shady business, or the stench of the python-filled kitchen of Serrailler’s chief suspect. And her characters are drawn with loving attention to detail. Here, for instance, is Serrailler sketching the cat: ‘He changed pencils, taking a soft 4B to shade in the thick ginger halo of fur down Mephisto’s back.’

But does Serrailler have the enduring appeal of an Inspector Morse or Commander Dalgliesh?

He is such a difficult character to read — is he just wary of women or emotionally callous? — that there is plenty of scope for Hill to flesh him out further in another book. His realisation that, ‘Sometimes there was no resolution. Sometimes you had to live with that’ is true but somehow unsatisfying. The Pure in Heart is not so much a psychological drama — Serrailler versus the criminal mind — as an engaging take on English provincial life, circa 2005.
