100 Years of Cox tells a family's history mostly in the family's own words. Those words come from the letters the ten Machell Cox siblings sent one another, which they called the 'budget' and which were still going round the globe in 1945. A great-grandchild of Edmund, one of the older brothers, chooses the letters, reads them out and adds dates, places and plain-spoken notes. Enid was the eldest. After Edmund came Arthur, Neville and Wilfred, then a younger set that included Bernard and Aldwyn. Aldwyn's letters come from furthest away. He was an Anglican clergyman with the UMCA, a mission run jointly by Cambridge and Oxford universities. He worked on its steamships in what was then Nyasaland and later became sub-dean of St Peter's Cathedral on an island in the middle of the lake. A two-part story, which the storyteller sums up as a crocodile and a murder, follows the death of his friend and colleague Padre Arthur Douglas in 1911. It goes on through the trial that held up Aldwyn's leave and his steamer voyage home by way of Zanzibar and Naples. The storyteller admits to not knowing where that trial was held or what happened to the Portuguese official involved, and asks anyone who finds out to get in touch. The small moments matter as much. Boys at the island mission pick out family members from photographs pinned to a cloth-covered board and admire Neville's and Bernard's moustaches. An episode set in 1912 visits the big old house in Wolverhampton where Enid lived with her husband Cyril, a schools inspector. The house is gone, and the storyteller shows where it stood by the streets that now cover the site. In a letter from Sydenham that October, Bernard describes Avis and Vera plunging into a little wood after blackberries and coming back with purple-stained lips. An episode on 1945, prompted by the eightieth anniversary of VE Day and VJ Day, gathers VE Day celebrations in Stamford, the siblings' reactions to the atomic bombs and their comments on the July general election. It also includes a letter about the Treasury questioning two repair bills for coal scuttles at a large hostel, until the writer proposes sending both scuttles to London. Another episode follows transport through the family's papers. It starts with Matilda, a third great-grandmother, travelling by carriage with a chaperone in the 1820s, and moves on through dog carts, governess carts and bicycles to motor cars. Along the way it finds room for a 1911 dinner with a new headmaster, the father of a future novelist, which Bernard thought not a very lively occasion. Vera, the storyteller's great-grand-aunt, writes in wartime of missing her family and of how welcome the budget letters are. Present-day asides are kept short: research at the Bodleian Library in Oxford, a talk on Vera at Great Comp in Kent, and a stop in Hobart, Tasmania, once a departure point for Antarctic expeditions. The appeal is the detail of ordinary life: ice in a flower vase despite a gas fire, Arthur's oldest holiday clothes falling apart, and a favourite sibling cheerfully admitted to.
