A 73-year-old woman from Greater Manchester has been missing in the French Alps since Sunday after going for a hike alone.
Retired teacher and great-grandmother Carol was last seen leaving for her daily walk in the afternoon and has not been in contact with friends or family since.
Ms Sheridan moved to the Haute-Savoie region of France two years ago after retiring.
According to the Liverpool Echo, she often goes for long hikes alone in the mountains, taking her black Fiat Panda to a remote mountain pass.
Police are desperately hunting for her car but say they do not know where to concentrate their search as she did not tell anyone where she was going.
Speaking to Manchester Evening News, Carol's desperate daughter Fiona Conyers, who lives in New Zealand, said: "The area in which she is thought to be missing is vast. We are relying on the public to help us find the car.
"If we find the car, we find mum, it's that simple."
Ms Sheridan settled in the small village of Habere-Poche, located around 80km from Mont Blanc, in the Rhone-Alps region.
A Foreign Office spokesman told the Daily Mail: "We are aware that a British national has been reported missing in France. We are providing consular assistance to the family."
