is not dated precisely, but can be presumed to be no later than 1904 (since it is referred to retrospectively in "The Adventure of the Second Stain", first published that year). The story features Holmes and Watson coming out of retirement to aid the British war effort. Only one other adventure, "The Adventure of the Lion's Mane", takes place during the detective's retirement. Personality and habits Watson describes Holmes as "bohemian" in his habits and lifestyle. Said to have a "cat-like" love of personal cleanliness, at the same time Holmes is an eccentric with no regard for contemporary standards of tidiness or good order. Watson describes him as While Holmes can be dispassionate and cold, during an investigation he is animated and excitable. He has a flair for showmanship, often keeping his methods and evidence hidden until the last possible moment so as to impress observers. His companion condones the detective's willingness to bend the truth (or break the law) on behalf of a client—lying to the police, concealing evidence or breaking into houses—when he feels it morally justifiable. Except for that of Watson, Holmes avoids casual company. In "The Gloria Scott", he tells the doctor that during two years at college he made only one friend: "I was never a very sociable fellow, Watson ... I never mixed much with the men of my year". The detective goes without food at times of intense intellectual activity, believing that "the faculties become refined when you starve them." At times Holmes relaxes with music, either playing the violin, or enjoying the works of composers such as Wagner and Pablo de Sarasate. Drug use Holmes occasionally uses addictive drugs, especially in the absence of stimulating cases. He sometimes used morphine and sometimes cocaine, the latter of which he injects in a seven-percent solution; both drugs were legal in 19th-century England. As a physician, Watson strongly disapproves of his friend's cocaine habit, describing it as the detective's only vice, and concerned about its effect on Holmes's mental health and intellect. In "The Adventure of the Missing Three-Quarter", Watson says that although he has "weaned" Holmes from drugs, the detective remains an addict whose habit is "not dead, but merely sleeping". Watson and Holmes both use tobacco, smoking cigarettes, cigars, and pipes. Although his chronicler does not consider Holmes's smoking a vice per se, Watson—a physician—does criticise the detective for creating a "poisonous atmosphere"
