Gretchen and I watched the premiere of "Whiskey Cavalier" last night. It's promising. It reminds us of "Castle", in that it's a buddy cop show (more or less) with a lot of sexual tension between the two leads. And although it's in the spycraft milieu instead of homicide, the feel is similar. There's a wider trail of bodies in this series, though. :)
We'll see how it develops, but you might want to give it a try.
