The Death Dealing Game (Frank Boff) by Nathan Gottlieb

The most original PI of the decade, Frank Boff teams up with the most flawed, toughest female investigator of the decade as suspended, hard-drinking cop Emily Lynch debuts. They make a deal: Frank helps her with her murder investigation, she helps him with a missing person investigation. When the cases collide there is hell to pay!
The introduction of Emily Lynch really makes the plot more exciting. There's some very great lines from this politically incorrect character that had me chuckling quite a few times.
I wasn't sure about the ending though. It seems Boff might be moving away from the Dark Side more and more, which I thought made the character so cool and interesting.
Anyway, another great entry in the Boff series. If you want to know a bit more and aren't sure if my word is good enough you can pick up a free copy of the first one in the series here for 2 days.
