Sins of the Sons (Keeper Marconi) by Vincent Zandri

What would happen if Spenser was written by Mickey Spillane instead of Robert B. Parker? That's kind of the feeling I had with this book.
Jack "Keeper" Marconi, former jailer and now PI is hired to prevent the old childhood friend of his new client to rat him out about a dark incident from their past. You see, they were involved with the death of a lawyer when they were young. When Marconi is asked by the cops to look into the case as well things heat up.
Aided by big and hunky black ex-con Blood (can you say Hawk?) he sleeps with an older woman, falls in love with a younger one and investigates the case until all secrets are uncovered.
There's a roughness to Marconi that reminds you of the old hardboiled days. However, in the use of technology it is clearly situated in the now.
It's pretty much an enjoyable story and although they reminded me a bit too much of Spenser and Hawk or Hardman and Hump main characters Marconi and Blood are entertaining guys.
I was expecting a bit more hardboiled fistfights and shootings though to spice things up, especially with the whole old pulp style.
