Ed Brubaker and Sean Phillips’ Sleeper is an excellent dark story about a super-powered secret agent who was sent to infiltrate a criminal organization as a deep-cover agent. When the book begins the only man who knows who Holden Carver really is is in a coma, and he’s getting in over his head in the organization.
There was a lot of awesomeness to love about this book. Holden Carver’s superpower is that he doesn’t feel pain and hals really quickly, but he can also transfer injuries that were inflicted on him to other people. So he gets shot, doesn’t feel the pain, touches you so you’ve been shot to the equivalent degree, and then he heals up while you don’t. He does a number of assassination jobs in service of the bad guys, but then he did bad things when he was a government agent too.
The book is set in the WildStorm universe, so there are a couple of references to The Authority, and the existence of posthumans is very well-established. One of the neat recurring bits is playing “origin stories” when they’re doing the boring parts of the job. It’s just one of those things that seems so right in a noirish crime book in a superheroic universe. (Ed Brubaker also worked on Gotham Central, another bunch of great noir stories in a superhero world.)
