An exciting new team of glamourous, crime-fighting, female detectives. Meet Oracle - the computer genius who used to fight crime as Batgirl, paralysed by the Joker but still very much in action, and Black Canary - the young adventuress who feels she has something to prove to the world. On their own, each is a formidable foe - together, they're a force to be reckoned with! Now, in this second thrilling collection of their adventures, Oracle and Black Canary investigate a vicious slave trader, run into some deadly female mercenaries, take on the powerful Kobra crime organisation, fight a prehistoric monster, try to bring a war criminal to trial, and hook up with Dick Grayson, the former Robin - now the superhero known as Nightwing!
