I'm currently reading Tea with Milk and Murder by H.Y. Hanna. This book is the second in the Oxford Tearoom Mystery series.
Gemma's mum has become the new chef at Gemma's tearoom and, much to Gemma's surprise, things are working out well, as long as you discount her mother's new found online shopping habit! The Old Biddies are also helping out in the tearoom as Cassie has been less than reliable lately. Cassie is besotted with a smooth art gallery owner, but Gemma has a bad feeling about this too smooth operator, and Muesli agrees. When a young woman makes a scene, then falls dead, during an art opening at Jon's gallery Gemma can't help but be suspicious of Jon, but will voicing her opinions cost her her best friend?
