We're glad to have you, Patil, but don't encourage Bobolis. He can be a chatterer. Oh, and I've had words with Frobisher, so that shouldn't cause any further trouble. No need for you to worry about it, at any rate.

As for the book, as soon as Troy's finished with it, I'm sure you'd be welcome to have it for as long as you need it. Let one of us know if you've got questions about any of the theory. It may be a stretch, but I feel sure you're up to the challenge.
