I couldn't decide between three and four stars for these three books. They held my interest throughout, had characters about whom I cared, good grammar, interesting plots. They were a little like others in this genre, though, P. I. with a buddy & a girlfriend & even in the third book, a dog. Still, they weren't an exact copy of anything else ... and I did like them quite a bit.
I look forward to reading the next book by this author, so I think I'll bump my rating back up to 4 stars.
