Wine tour of a lifetime? Come for the oak Malbec, stay for the pine coffin!

Twelve guests. Three perfect murders on a Christmas wine tour.

A serial killer hiding amongst the snowy vines.

The detective who will risk it all - solve the case to save their lives.

From the frosted vineyards to the blizzard-raged mountaintops, a dream trip gifts the once-celebrated detective Martin Moretti a shot at redemption. Trouble is, he'd prefer a shot of something stronger.

But when framed for the murders as well as the killer's next target, a breakneck race begins. Can the soberish Sherlock discover the truth before it's buried under the Alps with him?

Sideways meets Death on the Nile, a cosy comedy whodunnit for fans of Anthony Horowitz, Janice Hallett, Richard Osman, Bella Mackie and Mark Billingham's The Last Dance.
