Meet Lilly Tweed. Former Agony Aunt. Purveyor of Fine Teas. Accidental Sleuth.

It's Christmas in Plumpton Mallet, but it's not all holiday cheer and goodwill.

The festive season brings with it the biggest and most important event of the year for Plumpton Mallet, the annual Christmas Market. Attracting visitors nationwide, this time it's bigger than ever.

But there's one unexpected arrival who's not welcome, and he's out to cause trouble.

When a lifeless body is found outside Lilly's shop, she's shocked. But the arrest of one of her staff changes the shock to anger and compels Lilly to turn sleuth once more to prove their innocence.

Yet proving one person innocent means another must be guilty and this time Lilly might not be ready for the truth.
