After the world's top Spider-Man fan dies a little too coincidentally from a spider bite, and Comicdom's best-known Sub-Mariner expert just happens to drown mysteriously - not to mention a Human Torch collector burning to death - the FBI is forced to admit it is out of its league and must enlist the aid of a certain Peter Plippton, a.k.a., Dr. Marvel, the greatest Marvel comics expert on the planet, to stop the murders. But can even he, the awe-inspiring Dr. Marvel, unravel all the confounding comic-related conundrums to this case and stop the killer before another comic collector dies?
