FOUND HER!!!!
The dark and the snow and sight of a fox in the garden galvanised me to go looking and knocking on doors

I have to say the people in Hiolmsley Road were charming and helpful

i called on people who were out earlier and as we searched a garden I calle dand heard her next door where I had been three times today
They had they decking up earlier and although it had been replaced she was under it so called and shone torches and eventually saw her little pink nose and pink paws so hauled her out and put her inside my jacket

I can't tell you how relieved I am and grateful thanks to everyone who helped me
