Murder on the Mistletoe Express: the brand-new festive cosy crime to read at Christmas 2026!

A brand-new cosy Christmas mystery in the Three Dahlias series!

Rosalind, Caro and Posy are planning to take a much-needed break from investigating murder cases this Christmas for a winter getaway with their partners in the Swiss Alps. They've been invited to spend three days on a glamorous new luxury sleeper train, the Mistletoe Express, which Posy's boyfriend Kit is planning to invest in.

Travelling with them for the festivities are several other investors in the company. But the morning they depart, the company's administrative assistant, Olivia, is missing - just hours after warning Posy of a problem with the Mistletoe Express's accounts.

The three Dahlias' investigative minds are already whirring when, at their first destination, Olivia is discovered dead, despite never boarding the train . . .

It seems that the Mistletoe Express is brimming with secrets, and murder suspects.

Can the Dahlias catch a killer - and in time for Christmas?
