“But you had retired, Holmes. We heard of you as living the life of a hermit among your bees and your books on a small farm.”
Sherlock replies: “Exactly, Watson. Here is the fruit of my leisured ease, the magnum opus of my latter years, The Practical Handbook of Bee Culture.”
As quoted by Dr Watson in Conan Doyle’s “His Last Bow”.
If anyone has a copy of Holmes’ magnum opus, I would love to see it!
