Beekeeper Sherlock

Seems Ian McKellen is currently filming the role of the elderly Sherlock Holmes; what could be better?  Well, I'll tell you: in "His Last Bow" Doyle describes the ageing Holmes as retiring to the countryside and becoming a beekeeper and the author of a book about queen exclusion:

“Exactly, Watson. Here is the fruit of my leisured ease, the magnum opus of my latter years.” He picked up the volume from the table and read out the whole title, “‘Practical Handbook of Bee Culture, with some Observations upon the Segregation of the Queen.’ Alone I did it. Behold the fruit of pensive nights and laborious days, when I watched the little working gangs as once I watched the criminal world of London.”
