I actually greatly enjoyed this episode. The season has been a little stale (except the guest stars have been a hoot, overall) but this episode really saved it for me: very well done. The mystery of the shooting was (as always) trivial to figure out, but the mystery woman/cab driver was great, and Tony Shalhoub at the end did an excellent job. I thought for a second it was going to be really over the top, but it was actually quite touching. I thought Monk would realize that he'd never seen the woman before but that he knew her voice from some mystery or other, where he'd heard it on the phone or a tape or something. Having it be Trudy's eyes, and he unconsciously realized it but couldn't understand it, was very in character for him and yet still something we couldn't guess, and a nice reveal. Kudos!
