Adobe is having a bit of fun with Halloween this year and are hosting something a bit unusual... a murder mystery hidden in a Photoshop Document. The murder scene is a multi-layered PSD file for fans to explore and sort through using Photoshop. Can you solve the mystery? The official rules are below, but the concept here is pretty straightforward: download the PSD, sift through the layers and solve the crime. For those of you who love puzzles, this should be pretty fun.

Someone has killed Professor Photoheim at his annual Halloween party and we need Photoshop experts to solve this #PsMystery! Download the PSD from Creative Cloud: http://adobe.ly/1nLoD2p or directly here: http://bit.ly/1DnLenz. Additional clues and suspects will be released at 10 a.m. PT on Wednesday and Thursday, and the answer to who-dunnit will be revealed Friday at 10 a.m. PT. Readers can also follow along all week on the Photoshop Facebook page, and specifically the #PsMystery Facebook album.

So what do you think? Whodunit?
