Billy, 85, had total recall of a huge range of entertaining facts but after a trip home to his native Yorkshire, he returns to The Old Beeches totally devoid of any memory of who he is or of any of the amazing facts he used to be so proud to display.

Resident sleuths William and Sandy fancy a mini-break away from the home and take Billy back to Little Fell, the old mining town where he grew up. There they meet his daughter and his granddaughter, but discover that Billy not only alienated the whole mining community during the last miners' strike by supporting his pitman son in returning to work, but appears now to have lost the love and support of his daughter.
