 Originally written by Bruce Robinson (I) (qv) as a novel. Its  conclusion is quite different from the films: after his soliloquy  in the rain at the park, Withnail returns to the flat he shared with  Marwood, loads the rifle he took from Montys country home, pours  some wine (also taken from Monty) down its barrel, then puts the  muzzle to his lips and drinks. He then pulls the trigger on the gun,  killing himself.
