Mark Sennen was born in Surrey, but spent his formative years in rural Shropshire where he learnt to drive tractors and worm sheep. He has been a reluctant farmer, an average drummer, a failed Ph.D. student and a pretty good programmer. He lives with his wife, two children and a rather large dog, beside a muddy creek in deepest South Devon. He is the author of the DI Charlotte Savage series, plus the standalone thriller The Sum Of All Sins.
