Shadow Of The Cat! #323

In Batman #322, Captain Boomerang came to Gotham looking to get revenge on Gregorian Falstaff for losing his retirement money on the stock market. After some hilarious and fun fighting, Captain Boomerang's boomerang and Batman's Batarang collide... with the Batarang shattering the boomerang, and giving Batman the opportunity to take out the Captain. Meanwhile, Selina Kyle had hung up her cat-cape only to be diagnosed with a terminal illness that will take her life within the month. A mixture of herbs known to the ancient Egyptians is the only cure, but that recipe is long lost. The issue ends with the burglary of an Egyptian exhibit at the Riverside Museum, and the thief appears to be Catwoman herself.
