I am grateful to Glenn Shipway who spotted the following mention of Trollope in The Prime Minister and his Trollope; Reading Harold Macmillan’s Reading by Peter Catterall.
In his diary on 26 July, 1951, Macmillan wrote: “I have finished all the Barchester series, ending with Last Chronicles of Barchester (sic). This means that I have read all the clerical and all the political works again in the last few months, even weeks. This must stop. Trollope is a drug.”
