There is only one book I own that I know I will always want to keep. It’s small and unprepossessing, navy blue, about five inches by three, and is inscribed ‘Pte I. Masidlover’, who was my grandfather. A Book of Jewish Thoughts, selected by the Chief Rabbi Dr Hertz, was issued in 1942 to ‘His Majesty’s Jewish sailors, soldiers and airmen’. My copy also bears the stamp of another excellent name, Rabbi Dayan M. Gollop, Senior Jewish Chaplain to HM Forces. The book’s size means, I suppose, that it could be kept buttoned into a top pocket and taken anywhere.
