The Thief Who Stole Himself! Origin of Chameleon (Dmitri Kravinoff)
A fan recognizes MJ, asking for an autograph but thinks Peter is Irving Sprinkle from RS. 62.
Back home, Jonathon Caesar stops by and Pete gets a little jealous. Caesar returns home where he has a shrine dedicated to MJ. In Chicago, Peter and Ginny Edwards head to the next stop on his book signing tour is the Windy City! This should be a quick and easy trip to Chicago for the web-slinger! However an old foe from long, long ago elects to embark on a new criminal career in the second city!
Meanwhile, William Dukane heads home, where the real Dukane is held captive. The arriving Dukane turns into the Chameleon.
Peter arrives at the Science Expo, where Chameleon's gunmen start a diversion. As Chameleon abducts Dr. Edmund Debevic disguised as police Captain Turner. Spidey appears and slops the gunmen. Chameleon handcuffs Debevic and takes his place, planning to distribute his formulas to foreign powers. Spidey intervenes but Chameleon eventually escapes.
In the meantime back in Manhattan, the deranged Jonathan Caesar makes his move on Mary Jane!
At the Bedford Towers, Caesar and his hired thugs await MJ in her condo. He tells her what he wants is what he now has... Her.
Hurry home Spider-Man!
(Note: The Chameleon previously battled the wall-crawler in Amazing Spider-Man Vol.1 #186.)
