Murder sites in British crime fiction come in all shapes and sizes: West Country bookshops, greasy subterranean passages under Leeds Station and a twelfth century water mill have featured in my recent reads but, because of our climate we cannot do exotic. We can, however do windswept and bracing. Fitting that bill perfectly is a beach on the storm-lashed island of St Helen’s, one of the Scilly Isles. Home now only to gulls and kittiwakes, it remains the last resting place of the monks who once lived on the island. Scilly Isles copper DI Ben Kitto discovers a much more recent burial and, in doing so, he uncovers evidence of that vilest of vile modern ‘professions’, human trafficking.Kitto’s problems mount.

A new-born baby boy, just about alive, is left on the police station steps and DCI Madron, Kitto’s abrasive boss, is injured in an accident, and then disappears. The Scilly Isles must be a challenging place to be a copper. The islands that make up the archipeligo have, in total, the population of an medim-size English village, so crime ought to be easily solvable. But. And it is a very large ‘but’. Small boats are everything, and most people have access to one. The distances between the main inhabited islands – St Mary’s, Tresco, St Martin’s, St Agnes and Bryher – are relatively short, but the Atlantic Ocean is wild, unpredictable and unforgiving. Crime scenes are difficult to protect, forensic experts have to be flown in from Cornwall, and the frequently vile weather is a challenge to logistics and normal police procedure.

Kitto – who has returned to his birthplace after cutting his teeth in London with the Met – painstakingly gathers evidence about the dead girl and the abandoned baby, reluctantly reaching the conclusion that although international crime gangs may be at the root of the problem, the branches and leaves of this particularly poisonous tree are flourishing in the climate of his own bailiwick, and several prominent and well-respected individuals may be involved. Kitto is an islander to his core, but he is painfully aware of the challenges residence poses.

“The outside world is comfortless though. When I pull back the curtain, breakers are lashing the shore. Seabirds are returning to Bryher in flocks, scattered by the breeze.

It feels like we’re at the mercy of some savage force that’s trying to tear these islands apart.”

The old expression “barking up the wrong tree” has its origins in America, where hunting dogs would be fooled by their prey jumping between adjacent trees to fool their pursuers. It doesn’t sound as if there are many trees on the Scilly Isles, but Ben Kitto barks up at most of them in vain. This isn’t to say he is inept, or a fool. Quite simply, the villain is hiding in plain sight, too close to home. The final pages of Deadman’s Pool are exhilarating and graphic. When Kitto finally exposes the killer, I had to check back to see if Kate Rhodes had given us any clues, but I don’t think she did, so the surprise is even more startling.

I am a suburban man, root and branch, so it baffles me how anyone can remain sane living in such remote places as Barra, the Orkney Islands or the Scilly Isles. Kate Rhodes, however, has been bewitched by the charm of Island life, and she has written a gripping and addictive police procedural set in a frequently intimidating landscape. Deadman’s Pool will be published by Orenda Books on 25th September.
