The illustration depicts Batman doing battle with three members of the Court of Owls, a nod to the forthcoming crossover event 'The Night of the Owls'.
"In Detective #9, Batman finds himself in the unlikeliest of situations - saving Arkham Asylum administrator Jeremiah Arkham from a mysterious Talon assailant," said editor Mike Marts.
"What is the secret connection between the Court of Owls and Gotham City's oldest institution for the criminally insane?"
'Night of the Owls' gets under way this month with Batman #8.
