By David A. Gibb. The "disturbing true account" of Russell Williams's steady escalation from voyeur to stalker to killer. I seem to recall covering a Dateline about this guy on The Blotter Presents podcast back in the day...the case is a lot.
The book is in pretty good shape, mild corner- and edgewear (the things that look like nicks on the spine are part of the cover design), but clean pages, and an uncracked spine. A good reading copy.
