There's a fake Prowler in town, and the Vulture's after him. So is Spidey.
Looks like the phoney Prowler is at the building site for revenge. Seems he got fired while working his way through Med School. Spidey shakes Billy and gets involved, Prowler scarpers. Peter heads back to the hospital and figures that the new Prowler is probably some guy from the hospital who was on duty when Hobie was brought in after being paralyzed. Of course, that's the correct story, and the new Prowler plans to use the suit to rob folks' homes while they're in at the hospital being operated on. Not very nice!
Spidey starts visiting the home addresses of the interns who were on duty, and strikes gold first time. The fake Prowler is there, as is The Vulture. The battle would be brief, except that Spidey is suffering black-outs as an after effect of the Morbius bite back in Spider-Man #77. A dizzy spell at the wrong moment turns the battle, and gives The Vulture the upper hand.
These "dizzy spells" are a bit of a corny plot-device, but hey, you have to do something to give Vulture a bit of a hand. DeZago is doing all right with this stuff.
This isn't great, but it's better than what we were reading with Roxxon and Ka-Zar two months back, so let's give it a generous four webs.
