Yes! Sorry, got that confused. ^_^ (It's Sherlock Holmes pastiche where Watson is surmale and Holmes is male and the Irene-ish figure is female. Also they are desert-dwelling crab-people with three limbs. It's hard to find sadly but I enjoy describing it to people who think their Holmes AU is weird. ^_^ It even explores concepts of queerness in that society a little though of course not as much as I'd like.)
