The Old Girls' Network by Judy Leigh while not a cozy mystery with a murder, it is still, nonetheless, a cozy story. The type where you want to make a cup of tea and eat a chocolate biscuit while reading. I'm currently taking advantage of a three month free trial of Kindle Unlimited (I bought a Kindle Fire HD8 which was on sale recently).
Pauline, a well respected and liked neighbor in a small Somerset village, had difficulty with being alone after her husband's death when her 77 year old sister arrives. The sisters are completely different and rub each other the wrong way until Pauline accidently runs into, who she categorizes as a tramp, with her car. She offers him hospitality and as a house guest he clean himself up, tells the sisters that rather than being a tramp he had both his luggage and wallet stolen and was on his way to his chateau in France. With his Irish blarney he manages to build fences figuratively and helps Pauline with repairs to her cottage.
