“Velvet,” published by Image Comics, is your next spy thriller addiction. It is written by one of the best crime fiction writers that comics has ever known, Ed Brubaker. And he is teamed up with one of the best artists he’s ever worked with, Steve Epting. This new series blasts away from the start. We have the dark and moody color palette that Brubaker favors, provided by colorist Elizabeth Breitweiser. We have the nondescript lettering, as if out of typewriter or teletype machine, provided by letterer Chris Eliopoulos. Yes, this comic is like a good martini, shaken, not stirred.
