¹⁵⁵ Charles Walter Stansby Williams (1886–1945), an employee of the Oxford University Press since 1908, had published a number of what Jack called ‘theological thrillers’ before they met in 1936. Upon his arrival in Oxford he was quickly absorbed into ‘The Inklings’. Jack paid tribute to his friend in his Preface to Essays Presented to Charles Williams, ed. C. S. Lewis (1947). The best biography of Williams is probably Alice Mary Hadfield’s Charles Williams: An Exploration of His Life and Works (1983).
