Three Bedrooms, One Corpse is the third book in the Aurora Teagarden Mysteries by Charlaine Harris (known for the Southern Vampire Mysteries, basis for HBO's wickedly entertaining "True Blood", the Harper Connelly Mysteries, and Lily Bard Mysteries) . This is the fourth Charlaine Harris series I've read.
The heroine, Aurora Teagarden is a former librarian, who due to an unexpected inheritance, is now a lady of leisure. Score! Short, nearsighted, and heavily into true crime, she tends to stumble upon a lot of dead bodies. In this third novel, she begins an affair with the mysterious new older man in town, while also trying to figure out who keeps murdering local realtors.
I think this is Charlaine Harris' first mystery series, which would explain why Aurora Teagarden is the least clearly drawn of her heroines. Aside from her bookishness, lack of height, and fascination with murder, she doesn't have quite as much personality as her literary mystery solving sisters.
That aside, the books are entertaining, and I'll be devouring them as fast as my Kindle can download them.
