A puzzled pensioner keeps finding shop-bought eggs buried in her garden - and has no idea how they got there.
Rose Ritchie has found dozens of eggs hidden among her plants in the past year. She first spotted a shell while weeding last summer.
Since then, the 78-year-old woman found another egg lying on the grass, another in a plant pot, one on the edge of her pond and several more elsewhere in her garden.
Each has been stamped with different dates, The Lion Mark, which Rose says indicates the eggs have been bought from various supermarkets.
Rose, who lives in Studley, Warwickshire, said: "At first I thought a fox might have stolen them from a hen house and hidden them here for another time.
"Then I saw they had the Lion mark on them meaning they must have been bought from a shop.
"At the time there was a big Tesco at the top of the road but when that closed these eggs kept turning up.
"They've turned up everywhere and sometimes they are very well hidden."
Rose's family took to Facebook in a bid to solve the mystery, and was flooded with bizarre explanations and wild theories.
Some social media users suggested an animal was stealing the eggs from a nearby shop before stashing them in Rose's garden. Others said a prankster may be behind the eggs and others claimed it was a form of witchcraft.
"On one occasion last year I was doing some weeding and I dug down a couple of inches into the soil and I spotted this pink thing," Rose continued.
"I thought it was a stone until I picked it out of the dirt and realised it was an egg.
"But I don't think it's a prank because most of the eggs have been found in the back garden which is gated so someone would have to climb over each time."
Rose, who celebrated her diamond wedding anniversary with husband Joe, 82, in March, added: "It's an amusing mystery but I'd love to know the truth.
"I don't think it's a prank because most of the eggs have been found in the back garden which is gated so someone would have to climb over each time.
"Someone even suggested that it's a type of witchcraft whereby eggs are left at people's homes to steal their happiness.
"I don't really believe that theory. I personally think it must be an animal or a bird which is stealing the eggs from a supermarket on a fairly regular basis.
"The eggs are always unbroken and have stamps on them.
"We never eat them, instead I'm careful not to break them and I put them in the bin."
Rosie and Joe are now setting up secret cameras in a bid to find out who or what is hiding the eggs in their garden.
