Mystery Tales 
One of Martin Goodman's "Red Circle" weird menace magazines, seemingly published as a companion to Star Detective. Began with Vol.2 No.3, possibly to match the current issue of Star Detective.
BLACK POOL FOR HELL MAIDENS—HAL K. WELLS
Deep in that dismal swamp there dwelt an abysmal Thing, a monstrous being of the ooze, gloating in its perfume of cadavers . . . Kent’s horrified eyes must watch the girl he loved run stark naked to greet that grisly creature from hell!
BLOOD-BAIT FOR HUNGRY MERMAIDS—JOHN WALLACE
My Pamela would be the most beautiful mermaid of them all, and that was what mattered—not that a fiend’s fishhook would be torn from her lovely mouth, not that her lovely body would be split in two!
BLOOD FOR THE VAMPIRE DEAD—ROBERT LESLIE BELLEM
Was this then the horrible price Tim Croft must pay for his disbelief in devil-magic philtres?— forfeiture of his own lovely fiancee’s life-blood to the undead corpse of Haunted Hollow!
