Silencer Annual #1

"Silencer visits Gotham City, but she's not there to see the sights-she's there to shut down Talia al Ghul's latest secret weapons plant. Obviously, this brings her into conflict with Batman-but there's a secret history to Bruce Wayne and the Silencer that complicates everything! Will Batman slap the cuffs on this metahuman hit woman-or will one of Batman's rogues get the drop on them both for the mysterious Leviathan organization?"
