A Mother's Day Murder: A BRAND NEW mystery series from Number One Bestseller Mary Grand for 2026

'A fascinating whodunnit to stimulate even the most demanding of amateur sleuths.' T.A. Williams

Retired librarian Jessica much prefers the quiet comfort of her books to real-life drama. But when she travels to the picturesque village of Worth Stone on the Purbeck coast to visit her son Jack and his warm-hearted wife Beth, her peaceful holiday is quickly upended.

What is meant to be a gentle Mother's Day walk along the stunning cliffs takes a sinister turn when a member of their tight-knit group is found dead in a remote, thirteenth-century chapel. The police seem convinced that there has been no foul play but Jessica’s puzzle-hungry mind spots subtle clues they may have missed. Convinced that a murder has taken place, Jessica teams up with Beth to uncover the truth.

The unlikely sleuthing duo soon discovers that the idyllic stone cottages of Worth Stone conceal a tangled web of long-held grudges, simmering tensions and desperate secrets. With a circle of suspects who all had a hidden motive to kill, Jessica and Beth must race to unmask a murderer hiding in plain sight.

Number One bestselling author Mary Grand begins a brand new page-turning, edge-of-the-seat cosy mystery series, perfect for fans of Frances Evesham, Faith Martin and LJ Ross.

'I thoroughly enjoyed this intriguing mystery set in a beautiful location with deliciously menacing undercurrents.' Frances Evesham

Readers LOVE Mary Grand:

‘Everything about the plotting is superb - multiple twists, turns and misdirection... and that final pulling together of the threads and big reveal is so perfectly done - distinctly Poirot-esque.’

‘As with all of Mary Grand’s mysteries there are so many possible culprits and explanations, it is virtually impossible to discover the truth before the end. A great story with many secrets being gradually revealed that finally uncover the perpetrator.’

‘As always Mary never fails to amaze me. I normally read a couple of chapters at bedtime but last night I couldn’t stop until the end. Can’t wait for the next one.’
