"A Marshall Cavendish Weekly Publication" on the Yorkshire Ripper (aka Peter Sutcliffe) -- i.e., Dennis Nilsen's crimes. Published in 1989.
Some wear to the spine and corners of this stiff-cover magazine; mild warp to the book overall. But the pages are tight and clean inside, no tears or dog-ears, AND this is the "FREE Introductory Brochure," which also contains a precis of the series and another offer insert, all in a folder that's in decent shape for several decades old.
