Rabbi Small Mysteries - anyone know anything about them?

I am addicted to the "cat who" series, but I'm half way through it and trying to find a back-up. I like that the cat stories are mysteries, yet not too gruesome or riveting. I actually listen to them on CD as I'm going to sleep. (I save the Stephen King for daytime). The Rabbi stories look interesting, but are they sedate enough to go to sleep to?
