Mystery of Ruby's Mistletoe

Snowbound at Christmas.
Very cosy.
Until a murderer and a thief appear.
December, 1935.
Ruby and Fina are anticipating a quiet Christmas. But the snowy peace of Quenby College is shattered when the police come looking for Ruby. She and Fina escape to a relative's plush country home - only to find that Aunt Millie has a few surprises in store …
As the mercury drops, Ruby and Fina are drawn into a web of false identities and half-truths. Why did someone spike the cocktails during the after-dinner jazz? Who stole Aunt Millie's priceless hatpin collection? Could it be a coincidence that all the house guests were also present on the day when Fina's father was murdered?
With the police on their tail, and a killer on the loose, the two dressmaking sleuths have to use all their considerable wits to solve Fina's family tragedy - and bring a little joy back to Christmas.
