His Last Bow is a collection of previously published Sherlock Holmes stories by Arthur Conan Doyle, including the titular short story, "His Last Bow. The War Service of Sherlock Holmes" (1917).
The collection's first US edition adjusts the anthology's subtitle to Some Later Reminiscences of Sherlock Holmes. All editions contain a brief preface, by "John H. Watson, M.D.", that assures readers that as of the date of publication (1917), Holmes is long retired from his profession of detective but is still alive and well, albeit suffering from a touch of rheumatism.
Sir Arthur Ignatius Conan Doyle (22 May 1859 – 7 July 1930) was a British writer and physician. He created the character Sherlock Holmes in 1887 for A Study in Scarlet, the first of four novels and fifty-six short stories about Holmes and Dr. Watson.
