Batman and Scooby-Doo Mysteries, The #12

DON'T MISS THE FINAL ISSUE! There's a Phantasm haunting the Gotham City Opera House! Batman and Mystery Inc. are determined to exorcise this spirit before someone gets seriously hurt, owner "Theatric" Al Perry needs it to happen before his retirement fund gets seriously hurt, and Dr. Leslie Thompkins doesn't care about anything but acquiring the building to serve as a new neighborhood clinic so she can help residents who've been seriously hurt. Who will prevail?
