"Professor Callum and his wife are the parents of The Ds, Dick and Dorothea Callum. Professor Callum is an academic archaeologist, and is often correcting examimation papers. Neither Prof Callum or his wife have brothers, as Dick and Dorothea have no uncles of their own (WH23). But the Ds have aunts, as Dot thought of other aunts they knew, most friendly, kindly creatures (unlike the dreaded Great Aunt; PM3)). The Callum parents probably live in London: London last night, and now Beckfoot (PM2)."@en . . "Professor Callum"@en . .

Mrs Callum, accompanies Prof Callum him on conferences and expeditions. Mrs Barrable used to be her school-mistress, and Mrs Dixon used to be her nurse. It should be noted, therefore, that during Mrs Callum's childhood, Mrs Callum, Mrs Barrable and Mrs Dixon were all living in the same area; this could indicate that Mrs Callum is originally from the Lake region, like Mrs Dixon.
