This one made me laugh out loud a few times. Entertaining but brief Hollywood versions of Ryan and Esposito. The interrogation scene in "the police station" totally cracked me up. Great scene with the omniscient concierge at the boutique hotel.
Intriguing mystery surrounding the death of Kate's former partner, Royce, and the theft of some innovative untraceable bullets.
One scene just seethed with chemistry between Kate and Rick, but nothing comes of it, of course. I've grown to expect these teaser scenes. I find them annoying now, and utterly predictable.
The letter from Royce to Kate didn't right true, especially the advice to follow her heart with Castle.
Still, I really enjoyed this one.
