Three ways to kill someone in an untraceable way.*

My mother being a resourceful person with a large collection of blades which I know not how to dispose of, taught me early on how to poke someone in the eyes in an effective manner and gave me the three following recipes.

Method 1: the Borgia Duck.

This was apparently successfully used by the Borgias. You take a duck, plump and very much alive, and get a servant to run after it making a lot of banging noises to scare it almost to death. When the duck is suitably scared, you kill it and promptly cook it, then serve it to whomever you wish to dispose of. The adrenaline in the duck is meant to induce death.

Method 2: the Tiger Whiskers

Find a tiger, and get some of its whiskers. You chop the whispers finely and serve them mixed with rice, the stiff bits of whiskers being disguised amongst the rice grains. The whiskers will proceed in the gut, piercing it all over, producing a slow and painful death.

Method 3: the Potato and the Coffee

Take some green potatoes and boil them. Use the water to make some coffee. The mix of solanine from the green of the potatoes and caffeine should induce a fatal heart attack.

*disclaimer: having not actually tried and tested these methods, I shall not be held liable if this fails either in aim or legal proceedings and would suggest no ducks be harmed in the pursuit of nefarious activities.
