An extra-sized issue introduces Chase, soon to be starring in a new ongoing series, featuring some sequences by guest artists J.H. Williams III and Mick Gray. When the Clayfaces create a new, eerie version of themselves, Batman joins forces with Chase, a lady detective -- with an attitude -- who specializes in investigating paranormal activity. It's an uneasy partnership at best, and may give the Clayfaces the edge they need! 52 Pages, Cover price $3.50.
