Ichabod Crane is resurrected and pulled two and a half centuries through time to unravel a mystery that dates all the way back to the founding fathers.

I didn't start watching till recently but i have really gotten into it and there are plenty of episodes to get through to catch up (about 45 to date in 3 seasons).
Its kind of a mix of sanctuary/lost girl/haven with Sherlock Holmes in a more horror style like Grimm.
Well worth some time.
