Written by Paul Cornell and illustrated by Jimmy Broxton, the miniseries takes place in London and follows the exploits of Batman and Robin's British counterparts.
The publisher's solicitation reads: "In a secret bar within the city where peace is kept magically, heroes and villains gather to enjoy a pint and talk about their day. But what happens when the magical barriers that disallow fighting are dropped and a building full of heroes and villains confront each other all at once?
"Knight and Squire have to keep the peace and save both friend and foe in this six-issue miniseries."
Yanick Paquette has provided a cover illustration for the first issue. It will also be available with a variant from Billy Tucci.
Knight & Squire arrives in stores on October 13.
