BL Thrillers

Made thanks to a discussion under (now cancelled) Red Peafowl, thanks to @Heilin and @AmaiAkari. Not all are what I'd like them to be, and this is niche of niche but why not make a list?

"Series with main leads in gay/homosexual relationships, with vary degrees of elements of crime."  - is a more accurate title. 

Working list - please contribute
