GUEST-STARRING THE BLACK CAT! When Reed, Ben and Johnny leave on a fishing trip to the Negative Zone, Sue Storm and Alicia Masters are left to their own devices. And no sooner have the guys left, than Susan's number-one, absolute least-favorite person in NYC starts banging on the door of the Baxter Building. She's wanted for murder, she's being chased by the police and she's covered in blood: That's right — it's Felicia Hardy, the Black Cat! Despite all the evidence pointing to her, Felicia claims she's innocent — and she needs the Invisible Woman to prove it! Against her better judgment, Sue agrees to help and soon finds herself embroiled in both a murder mystery and a science mystery that may be impossible to solve... while Felicia Hardy's life hangs in the balance.
