According to A Day by Day Chronology of Mr. Sherlock Holmes according to Zeisler and Christ, compiled by William S Dorn, on June 11, 1900, Lestrade consulted Holmes about the theft of busts of Napoleon. [SIXN]
“Anything remarkable on hand?” he asked.
“Oh, no, Mr. Holmes, nothing very particular.”
“Then tell me all about it.”
“Well, Mr. Holmes, there is no use denying that there is something on my mind. And yet it is such an absurd business that I hesitated to bother you about it. On the other hand, although it is trivial, it is undoubtedly queer, and I know that you have a taste for all that is out of the common. But in my opinion it comes more in Dr. Watson’s line than ours.”
“Disease?” said I.
“Madness, anyhow. And a queer madness too! You wouldn’t think there was anyone living at this time of day who had such a hatred of Napoleon the First that he would break any image of him that he could see.”
I love this passage, and the way it shows the friendly relationship that’s developed over the years between Lestrade, Holmes, and Watson. Lestrade just pops round from time to time for cigars and a chat about what’s new in London crime. –Selena
