Corpse in the Kitchen — Sarah J. Mason

RISING CRIME
She was baking bread--until an unknown party turned the staff of life into the stuff of death... and choked her with a wad of raw dough. Now the heat is on... and only Trewley and Stone can find out who cooked up this fiendish murder...

MEET TREWLEY AND STONE
Detective Superintendent Trewley has years of experience probing the dark secrets of cozy English village life. But even he can use a bit of help sometimes. That's where Stone comes in: with the mind of a scientist and a black belt in judo, she's the perfect partner for tough old Trewley... and together, they're the perfect crime-solving team.
