Answer:
Baltus Van Tassel: The horseman was a Hessian mercenary sent to the shores by German princes to keep Americans under the yoke of England. But unlike his compatriots, who came for money, the horseman came for love of carnage.
Ichabod Crane: The millennium is almost upon us. In a few months, we will be living in the nineteenth century. But our courts continue to rely on medieval devices of torture
High Constable: Stand down.
Ichabod Crane: I stand up for sense and justice.
Reverend Steenwyck: Their heads weren't found severed. Their heads were not found at all.
Ichabod Crane: The heads are... gone?
James Hardenbrook: Taken. Taken by the Headless Horseman. Taken back to hell.
Brom Van Brunt: We haven't heard your name yet, friend.
Ichabod Crane: I have not said it.
Ichabod Crane: Doctor Lancaster, Reverend Steenwyck, Notary Hardenbrook, and Magistrates Philipse, who tried to cut and run, and lost his head. Four frightned men, arguing on the very night Magistrate Philipse was killed. There's a conspiracy here. The doctor, the reverend, the notary, and the magistrate. What is the secret that unites them? Magistrate Philipse knew there were five bodies to four graves, knew the widow was pregnant, but would not tell me the name of the father. What does this point to? We must proceed by a process of elimination. I shall make a list of every man and woman in Sleepy Hollow, starting with their chief citizen, Baltus Van Tassel. I feel we're getting very close.
