Thanks for that. I didn't realize you needed to scroll, so I thought the Pink Floyd reference was supposed to open the shop or help access Willow.
I got through but did encounter something that I'm pretty sure was a real bug at the very end. I used something that wasn't the code to unlock the safe (not exactly sure but I think it was the jewelry receipt). Because of this I was one piece of evidence short on the first murderer. On a subsequent playthrough, I made sure and used the code and was able to solve the case (in 15 days).
Cheers :)
