Scandal at the Salty Dog by Josh Lanyon
I'm thoroughly enjoying this series. It's light and fun with just enough tension thrown in. Of course, it does have everything a cozy should have - an amateur detective, a bookstore, a dog, a quaint town, quirky secondary characters, and a sexy love interest. And of course, Ellery finds himself in danger on a semi-regular basis. This is a series best read in order. While the mystery is confined to this book, you'll understand the characters' backgrounds and relationships better if you start from the beginning.
This time around Ellery finds himself in the middle of two mysteries. First, someone's breaking into the Salty Dog pub and stealing food. Second, Mrs. Blackwell is being haunted, well, maybe not haunted - Ellery doesn't believe in ghosts, but someone uninvited has definitely been in her house. Of course, the two are connected, but it takes a bit to figure out how.
Ellery and Jack are finally kinda dating in this one, which is nice....
