Avenger Double Feature Softcover

"From the creators of Doc Savage and The Shadow! Two new thrillers for the price of one! Black Water is a secret worth killing for, a prize worth any price to claim. To most, it is a myth, but for the leaders of the Tartarus Legion, it is an obsession. And, when a distraught woman comes to the Richard Benson with a story about the ghost of a vicious mass murderer, he and Nellie Gray find themselves targeted by a ruthless killer. Has the fiend really come from beyond the grave? And will he take the Avenger and Nellie back with him?"
