Grandmother poisons her entire family with chocolate that went out of date 25 years ago

Three generations of the same family were poisoned when a grandmother accidentally used a sachet of chocolate that was 25 years out of date. Richard Hartley-Parkinson for Metro.co.uk

So let me get this straight – she spent decades playing the part of the friendly, loving, innocuous mother; years gaining the trust and admiration of her grandchildren; then – after meticulous research and planning – bought some chocolate sachets and waited twenty-five years to use them to poison her entire family? What sort of fiendish criminal mastermind are we dealing with here? Most people want to kill their family as soon as possible; they certainly don’t wait for the grandkids to grow up so they can get them too. Well, you know what they say – revenge is a dish best served cold.
