Silent Partner is a tie-in for the TV series Diagnosis: Murder (starring Dick Van Dyke). I think I maybe caught an episode once, about eight years ago. I picked this up at the library because I regularly read Lee's blog. This is pretty typical stuff for a series whodunnit - to his credit he managed to keep me guessing until about two-thirds of the way in. Since I came without any background about the characters, there was a lot of interaction that was lost on me. I assume the 'Jack Stewart' who reappears to do a kidney transplant was someone who left the show, but without that context his introduction didn't make much sense.
