Muffins and Mourning Tea

Cotswolds tearoom owner, Gemma Rose is excited to join the May Day celebrations in Oxford... until the beautiful spring morning ends in murder.
Now, she's embroiled in a deadly mystery - with four nosy old ladies determined to help in the sleuthing! Before she knows it, Gemma finds herself stalking a Russian "princess" and keeping up with the Old Biddies in Krav Maga class, while still trying to serve delicious cakes and buttery scones at her quaint English tearoom.
And that's just the start of her worries: there's her little tabby cat, Muesli, who is causing havoc at the local nursing home... and what should she do with the creepy plants that her mother keeps buying for her new cottage?
But the mystery that's really bothering Gemma is her boyfriend's odd behaviour. Devlin O'Connor has always been enigmatic but recently, the handsome CID detective has been strangely distant and evasive. Could he be lying to her? But why?
