Finished yesterday and I wouldn't rate this one best in the series, despite my soft spot for heists/capers (mainly in film). It was a good entry, but for one thing it stretched the "beating the hell out of Harry" motif a bit beyond belief.
The movement from act to act also seemed rather mechanical. Butcher's gift, IMO, is proceeding on formula but lending it a naturalistic feel. Here, the early movements were smooth enough but the later movements seemed telegraphed well in advance to the point that much of the latter third of the novel was just busywork. There was a grand scene toward the end, telegraphed or not, but I can't count this novel as Butcher's best work. Its redeeming virtue, as usual, was the character development. Movement of the larger arcs seemed to happen almost independent of the main action in this book, but it was still significant.
