The Spider #16: The City Destroyer

I don't recommend these books.
They are terribly violent and gleefully violent as well.
A high ranking Police official says to the “hero”,
“You're needed, too, Dick,” he said quietly. “Don't forget that this is only the beginning of the battle. As usual, I'll be hampered by the confounded laws. We ought to take this Devil Hackerson and torture the truth out of him.”
The plot, involving destroying things to increase the value of the bad guys stocks, is both horrifying and current.
The descriptions of the catastrophes are intense, taking me back to 9/11.
If you want to read some old timey pulp stories, stick to Doc Savage.
