Since Yonah is almost certainly our point of contact  and probably takes care of question 1 I'm going to go ahead and elaborate on my earlier answers to questions 2 and 3.<br/><br/><strong>What have you seen that makes you think there's more to this?</strong>On the book being a ledger for a business or the government. Ledgers imply cooked numbers, shady business deals that people would rather keep hidden, and most importantly connections to criminal enterprises. A ledger can reveal a surprising amount of what's going on behind the scenes and help give direction. My other suggestion of it being a book from Lord Scurlock should be pretty self explanatory. The guy has been in the city forever, knows the webs of power like the back of his hands, and is a good way to help give us an introduction to stuff that seems simple at first but has a great deal of stuff going on behind the scenes. Also a possible link to more supernatural stuff.<br/><br/><strong>What plan do you have to take care of this matter?</strong>I'm still of the opinion that a stealth plan is the best here although a deception plan where we pretend to be buyers and trick the thief out of the book could be fun too. For stealth we could track the thief to his home break in from passage to one of the many canals or the back alley, locate and steal back the book. I imagine if we've been hired or pointed in the direction to take care of this book thief for some reason instead of the blue coats the client or whoever it is that wants the book back would prefer discretion instead of us jumping the thief and mugging him or beating the crap out of him to retrieve the book. That kind of stuff seems bound to attract the bluecoats and attention we don't want.
