Request #242

I’m looking for a book I read in 1976-77. It could have been published in the 1960’s or 1970’s. It was a compilation of spooky short stories with some sort of figure in the cover. One story talks about heroin as “rat’s poison.” The story I remember most is about a red-haired boy name Rusty who drowned, but whose ghost saves another boy from drowning. I would love to find this book again.
