Batman:
Alfred. Are you there?
Alfred:Yes, Master Bruce. How may I help you?
Batman:I'm still in pursuit of The Riddler, but I've run into a problem. I've been trapped in a room with a piano, and two paintings on the wall. One of these paintings is cryptic, even by Nigma's standards. The other appears to simply be a single measure of sheet music. The rest of the room is bare.
Alfred:What of the piano, Master Bruce? Have you found any clues there?
Batman:I've examined it, thoroughly, but I don't see any way to get inside. The casing appears to be titanium alloy composite, and I can't find any cracks. I've scanned the piano, and it's clear that it is somehow connected with the doors to the room. I fear that hitting random keys, however, will just cause the doors to lock permanently.
Alfred:Allow me to see the paintings, then, if you wouldn't mind?
Batman:Here. I'm sending images of them, now.

Alfred:
How curious, Master Bruce. Let me think...
Batman:Alfred, Nigma's getting away, and there's a bomb, somewhere in this building!
Alfred:Right. If you wouldn't mind, sir, I know of a group of people to whom I could send this information who would likely be able to assist in solving it.
Batman:Go ahead, but make sure they understand..
Alfred:We're in a hurry. Understood, sir. I'll get back to you.
Alfred: You are those people. Could you please do your best to assist us? Thank you, ever so much. I've included the transcript of mine and Master Bruce's conversation, in case it helps, at all.
