I just found this series this winter (just before the holidays) and have only read one book so far. It reminds me of Jim Butcher's Dresden Files, which have become another favorite of mine. In fact, I wrote the down the following exchange because it was just too funny (& there are times I wish I could say it!):

<i>“You can’t talk to me like that,” said Ffinch-Thomas, his voice so strained it was practically breaking.
“Of course I can. I just did. Weren’t you paying attention?”</i>
