This is a Halloween Horror: it will pop up when Halloween comes close, and I hope you find a way to make use of it.
The Tale of Harrot, the Headless Horseman is a weird supernatural encounter for Lamentations of the Flame Princess(tm), but may be retro-fitted to other OSR games by changing the names of the Saving Throws and adjusting the Armor Class (AC) of the one and only enemy of the scene. It is best suited for characters beneath 5th level, especially if the group contains a cleric (who at this level may simply banish the sole threat of the evening with a Dispel Evil). A group of 1st level may end up losing a PC or more, but as it is a Halloween Horror (and LotFP seems to be proud of its mortality rate at times) this may not be a bad thing.
The encounter will fit into any pseudo-fantasy world or alternate history in a period somewhere between the 14th and late 15th century. The encounter needs the PC to be traveling from A to B in a rural and sparsely populated region, and they should not be willing to accept a delay of a day or more. On their way, the characters will pass through the small village of Oakhill (little more than a hamlet), perhaps just to take a meal and a crap before moving on, or to spend the night in the Old Oak inn. The inn keeper will advise them to stay a little longer, and tell them a story...
