[Breedinglikeone]

Eveining All. I am deperately trying to find a lovely book from my long ago choldhood about a housemouse who lives in Jonathan's dolls house and eats chocolate biscuits!! Its so lovely but I can't find it on Amazon.. does anyone know what I'm talking about?!

Is it 'The House Mouse' by Dorothy Joan Harris?
Amazon description (used copies available) -"Four-year-old Jonathan's new friend Mouse takes up residence in his sister's dollhouse - but only in the winter months."
