Gregg Taylor has spent eight years as the faithful raconteur to the masked protector of 1930's Toronto, The Red Panda, whose two-fisted adventures he has recounted in Decoder Ring Theatre's award-winning radio drama series The Red Panda Adventures, and in the Tales of the Red Panda prose pulp-hero novels. All told, he has written more than 150 full-cast radio drama scripts for DRT, and is the author of several other books, including the science fiction thriller Finn's Golem and the detective novel Black Jack Justice. Gregg lives in Hamilton, Ontario with his beautiful wife Clarissa and his children Max and Tess, who have no idea that the Red Panda is not as famous as Batman, so please don't tell them.
