It's the day of the Christchurch Dog Show. The whole town is aquiver with excitement. The ladies of the Charity Shop Detective Agency are hoping to make lots of new furry friends.

After a very dramatic Best Biscuit Catcher competition, Fiona, Sue and Daisy, from the Dogs Need Nice Homes charity shop, come across a shocking scene.

The dog show's vet is performing CPR on a woman. The ladies rush over, but it's too late.

Back at the shop, the ladies are shocked to learn that the poor woman was murdered. Someone injected Sylvia Steadman with something very nasty indeed.

Then our silver sleuths uncover that Sylvia was the owner of ex-Crufts-winner Charlie. She must have had lots of very jealous competitors . . .

There's barely time for elevenses. The charity shop detectives must roll up their sleeves - they have a killer to catch.

Fans of The Thursday Murder Club, Janice Hallett, Simon Brett, Ian Moore and Sarah Yarwood-Lovett will adore this exciting new talent in cozy crime.
