Looking for a Kirk/Spock STXI fic

[sailorandme.livejournal.com]

hello everyone,
this is a little bit of a long shot, because i don't remember much, but i am looking for a specific fic belonging to the reboot timeline.

i think it was probably posted in 2009 (if not then 2010), and around october because i'm pretty sure it was written with halloween in mind. from what i can remember the fic takes place onboard the enterprise and they're having some kind of exhibition with alien art and artefacts. one of these artfacts has an influence on the mood of the room, or it changes them some how - i'm pretty sure the fic was written partly as a murder mystery/almost detective novel kind of way.

that's all i can remember but i'm also sure that there was a kirk/spock subplot (because that is mostly what i read), and that it featured some well written original characters. i have tried to google and look for it myself but have come up empty handed - if anyone can help i'd be so so so glad!
