Yes! Sherlock Holmes will be around to help solve this mystery! (and as an FYI, he's the kind of guy who will improvise by, say, bringing his own mirrors to redirect the beams of light to places they normally wouldn't reach. He's not opposed to cheating the system if he thinks it'll get him results)

Sadly, I have a very limited window of time on sunday when I can be online. I should be able to do some minimal plurking while I'm at work, but I can't type anything too extravagant on my little smartphone.
