Synopsis of the short story

Following his departure from Baker Street, Dr Watson, although busy with his medical practice, decides to call upon his old friend, Sherlock Holmes. Holmes’s page, Billy, informs the doctor that the over-worked detective is actually asleep in his room, although curiously there is a life-size wax dummy of his old friend positioned by the sitting room window. In the midst of this odd scenario, Holmes appears to explain that he is investigating a baffling and perilous case involving the disappearance of one of the crown jewels, the famed Mazarin stone. At this point, Holmes’s principal suspect, Count Negretto Silvius, calls at Baker Street and Watson is hastily dispatched to fetch Inspector Youghal from Scotland Yard. In the meantime, Holmes proposes to detain the elegant and dangerous jewel thief himself…

Next time on Doings of Doyle…

We begin our exploration of Conan Doyle’s breakthrough novel, Micah Clarke.

Synopsis

There have been many theories forwarded regarding the fate of the brig Marie Celeste, found drifting derelict in December 1873. But one man, Dr. J. Habakuk Jephson, knows the truth because he is the only known surviving passenger. Following service with the Union forces in the American Civil War during which he was badly wounded, Jephson settled down to regular medical practice in Brooklyn. But years of overwork, weak lungs, and the lingering effects of his war wound leave his own doctor to suggest recuperation via a long sea voyage. Unfortunately, the chosen vessel is Marie Celeste, whose passenger list is expanded by the last minute addition of the apparently wealthy Septimius Goring, a man of mysterious and sinister aspect and antecedents. At first, all goes well, until the captain’s wife and child are tragically lost overboard mid-Atlantic, following which the ship appears to be cursed…

Synopsis

Major Errington is one of the most respected and popular officers in the Third Carabiniers, a veteran of numerous campaigns as both a soldier and a war correspondent. He is quiet, self-effacing and wise; he is also rich, but far from ostentatious. He is in fact more notable than the regiment’s nominal commander, Colonel Lovell, who is not unpopular but granted a degree of favour for his widely admired daughter, Violet. Lovell, or the Chief as he is known, is at heart an old-fashioned plunger who loves horses and gambling, but has also taken to playing the stock market and has had his fingers badly burned in American railway speculation. To recoup some of these losses, he takes to high-stakes games of écarté with Major Errington with little success. And then a rumour takes hold that the Major may be cheating…

Synopsis

Following the collapse of a city firm and the loss of his capital, John Hudson is forced to find an affordable place to live while he waits for legal restitution. He fixes upon the Austrian Tyrolean village of Laden where he settles into a contented if somewhat dull existence, enlivened to some extent by the presence of the intellectual village priest Father Verhagen. This placid atmosphere however is shattered by the gruesome murder of one of the villagers. At first, the killing is blamed on an itinerant Italian pedlar with whom the victim had quarrelled, but the police have to release their suspect when a second and more prominent villager is also murdered and a reign of terror begins…

Synopsis

During the opening stages of General Sir Herbert Kitchener’s reconquest of the Sudan in the 1890s, a trio of British correspondents has become detached from the main body of Kitchener’s force. The group prepare to bed down for the night in a palm grove when they encounter a lone British railway engineer in a heightened state of agitation. Naturally, they scent a story in the air. Shortly afterwards, they encounter the engineer again. Shots ring out, accompanied by a small party of Mahdist warriors. The correspondents are armed but nevertheless this is real danger. It is also copy, and what is danger when each man here owes a level of duty to his editor and, of course, his readers…
