He'd previously gone through extreme lengths to protect his brother, and it seemed like he could do little of that here, at least with his usual methods. But, when it came down to it, even Mycroft Holmes would endure...legwork...if he must.]

Have you kept notes, or any sort of record? I should like to see them, if so.

[If Sherlock couldn't figure it out, perhaps he could.]
