Showbiz comes to Oxford in the form of Britain's hottest new talent show and tearoom owner Gemma Rose gets a peek behind-the-scenes when she's asked to cater for the event. But with the Old Biddies entering the contest as England's first "granny band", and her little tabby, Muesli, taking part in one of the acts, Gemma soon ends up with more than she bargained for... and that's before she comes across a frozen dead body! Now, she's on the trail of a murderer, with four nosy old ladies giving her a helping hand, while also dealing with her embarrassing mother, her workaholic boyfriend-and even a mouse invader at her tearoom! With things hotting up in the contest and so many suspects in the running, can Gemma catch the killer before the curtain falls?
