The film novelization vs. the original short story

Legend of Sleepy Hollow: Novelisation - Peter Lerangis

So I like this novelization because it was a lot like the film and it was fast paced and atmospheric which I love, it's one my favourite films. I like the fact that Ichabod Crane is terrified of spiders because I am as well they creep me out, but I don't really understand how he can be a constable in the New York Police Department if he is squeamish about blood or corpses when he has already dealt with people that have been murdered.

However the original story was very detailed about anything other than the headless hessian soldier and why sleepy hollow was cursed or why and how the headless horseman was resurrected.
