William Bishop

 was a private in the Green Jackets 5th Battalion stationed near Plymouth. He was called in to assist the pile up on the A38 Liskeard Bypass. He was assigned to Colonel Lethbridge-Stewart and helped in combating the Yeti in Bledoe. He took a shine to Anne Travers when he met her. He used to love reading science-fiction novels when he was a kid. Lethbridge-Stewart considered Bishop to be good officer material, and decided Bishop would make a good addition to the special team he planned on building. (PROSE: The Forgotten Son)
