A quiet life. A deadly secret. How far will she go to settle the score before it’s too late?

Gardening enthusiast, Philippa "Pinkie" Floyd infiltrates a Cornish country club with a deadly mission: to eliminate Judge Carlisle. Armed with the deadly rosary pea, a revered tool among poisoners, Pinkie meticulously plans her strike. To her fellow gardening fanatics, she appears as just another retiree seeking solace in Cornwall's tranquil beauty, but beneath this facade lies a calculated expert with a singular focus.

A seasoned professional, she never mixes work with pleasure. However, with the law closing in and ghosts from her past resurfacing, Pinkie must choose between her retirement and the most perilous mission of her career.

The fourth installment in Julie Evans's The Cornish Crime series, The Poison Promise is a page-turning tale of vengeance, betrayal and the blurred lines between justice and retribution.
