Moving on from arsenic, we come to cyanide. Is that a kind of maturity? Like going from cheesy triangles to morbiers? What I know about cyanide comes from Agatha Christie or somesuch and is, in totality: smells like bitter almonds. So, you think, why would anyone drink it in their coffee without first wondering if their nearest and dearest were trying to kill them. Answer: because almost certainly Starbucks has an almond syrup latte that has breathed new life into the wife-poisoning industry. Then again people are always knocking back cyanide in their champagne in Christie without complaint, until their hand flies to their throat, their face contorts into a hideous mask and they fall writhing and then lifeless to the ground. Miss Marple and M. Poirot only have to bend their heads down to the lips of the corpse to get a whiff of almonds and know exactly how, why and who done the deed. I suggest you just say no if your beverage smells of bitter almonds.
