Basil I, called the Macedonian (Greek: Βασίλειος ὁ Μακεδών, Basíleios hō Makedṓn; Armenian: Բարսեղ Ա Մակեդոնացի, Barsegh A Makedonatsi; 830/835 – August 29, 886) was a Byzantine Emperor of probable Armenian descent who reigned from 867 to 886. Born a simple peasant in the Byzantine theme of Macedonia, he rose in the Imperial court, and usurped the Imperial throne from Emperor Michael III (r. 842–867). Despite his humble origins, he showed great ability in running the affairs of state, leading a revival of Imperial power and to a renaissance of Byzantine art. He was perceived by the Byzantines as one of their greatest emperors, and the dynasty he founded, the Macedonian (Greek: Μακεδονική δυναστεία), ruled over what is regarded as the most glorious and prosperous era of the Byzantine Empire.

Sherlock Holmes ( /ˈʃɜrlɒk ˈhoʊmz/) is a fictional detective created by Scottish author and physician Sir Arthur Conan Doyle. The fantastic London-based "consulting detective", Holmes is famous for his astute logical reasoning, his ability to adopt almost any disguise, and his use of forensic science skills to solve difficult cases.

Holmes, who first appeared in publication in 1887, was featured in four novels and 56 short stories. The first novel, A Study in Scarlet, appeared in Beeton's Christmas Annual in 1887 and the second, The Sign of the Four, in Lippincott's Monthly Magazine in 1890. The character grew tremendously in popularity with the first series of short stories in Strand Magazine, beginning with A Scandal in Bohemia in 1891; further series of short stories and two novels published in serial form appeared between then and 1927. The stories cover a period from around 1880 up to 1914.

All but four stories are narrated by Holmes's friend and biographer, Dr. John H. Watson; two are narrated by Holmes himself ("The Blanched Soldier" and "The Lion's Mane") and two others are written in the third person ("The Mazarin Stone" and "His Last Bow"). In two stories ("The Musgrave Ritual" and "The Gloria Scott"), Holmes tells Watson the main story from his memories, while Watson becomes the narrator of the frame story. The first and fourth novels, A Study in Scarlet and The Valley of Fear, each include a long interval of omniscient narration recounting events unknown to either Holmes or Watson.
