The Black Hand
The difference between Cyrus Barker and Sherlock Holmes is like the difference between Daniel Craig's James Bond and Sean Connery's. I've never been able to watch a Sean Connery James Bond movie (though I like him enough in other projects). He always seemed more than a little ridiculous and not at all dangerous... unless you're a woman. With Holmes, while I like the tales enough, Holmes isn't much of a person to me. Watson even less so.
On the other hand, Will Thomas's characters jump to life. Barker is a bit of a superhero, but not so much that he would need a cape. In this installment, he takes on the Mafia, a secret Italian criminal society just then getting a foothold in London. Of course, the mission gets accomplished, but unlike a Holmes story, one guy gets stabbed in the face and another has his knees broken for him.
Another great read in the series.
