Query: Flippancy Does Not An Engaging Novel Make

I wanted to like this book because I'd heard positive things about it, also because it supposedly treated BDSM in a realistic & intelligent fashion. Unfortunately, this is one of those books whose characters are immediately annoying & the narrator's voice is hopelessly flippant and arrogant. One third of the way into it and I was hoping the main character Perry would end up with a ball gag in his mouth and his hands chained somewhere far from his typewriter keys. Alas, it wasn't to be. This book may be breaking new ground, joining the mystery genre with that of erotic fiction, but it just doesn't read very well.
