"Secrets shared years ago between Bruce Wayne and Tommy Elliott-- a.k.a. Hush-- come to light with dangerous consequences in the present! Guest-starring Catwoman, this new hardcover ties directly into the "Batman R.I.P." event and collects DETECTIVE COMICS #846-850. As Batman finds himself barely capable of handling the diabolical threat of the Black Glove, Hush attacks Bruce Wayne in his personal life by setting his sights on Bruce's ex-lover: Catwoman!" -- from publisher's web site.
