Norton Glover commented on Doctor Death Vs. The Secret Twelve, Volume 1 by Will Murray
I've finished the first novella in this - "12 Must Die". It's honestly a lot. Dr. Death is apparently a super-scientist with occult powers who uses hypnotism, death rays, Communist agents, and a literal army of zombies to fulfill his goals - ending science and industry in order to drive humanity into a new Dark Age. His method is to murder leading scientists, businessmen, and engineers.
Basically he's Dr. Doom with Ted Kaczynski's ideology.
As is common in old (and modern) pulp tales, the plot doesn't slow down for a second. One wild action scene after another. I was expecting all this, but not so much of it. Like junk food, Dr. Death is best consumed in small doses.
