We were once called to a council flat in London occupied by a Chinese gentleman. He had not paid his rent in over eighteen months and eventually the council entered the property to repossess it. They were shocked to find the tenant in bed, wrapped tightly in his duvet like a cocoon. He had died in his sleep over a year before and was almost totally skeletonised. The bedding and mattress had acted like a wick, drawing away all the moisture produced by decomposition, leaving the remaining soft tissue desiccated and effectively mummifying him.
