Good Miss Silver mystery, it's one of my keepers. Most of Patricia Wentworth's books are worth reading. They were mainly written in the 1930's and 40's, and are in the English country house murder mystery genre. There is always a romantic subplot and most of them feature the private detective Miss Silver(think Christie's Miss Marple). They are all out of print, and most of the ones I've collected came from used book stores. Many of them are going for way over the original cover price on Amazon now, so if cozy British mysteries are your cup of tea, I would grab them here.
