The Deep is an Outsiders volume written by Peter Tomasi and illustrated by Lee Garbett. It's published as part of the Batman: Reborn crossover, establishing the Batman Family status quo following Battle for the Cowl and Bruce Wayne's disappearance during Final Crisis. The other stories published simultaneously include Batgirl Rising, Batman Reborn, Elegy, The Grail, Hush Money and Long Shadows and Union. This is the beginning of Tomasi's Outsiders volume, following from the conclusion to Frank Tieri's Batman and the Outsiders with Batman R.I.P. and followed by Tomasi's second arc The Hunt.
