Sherlock Holmes - The Waterloo Colour and Other Stories

Ensign the Hon. Ian Lewin, 112th Foot, deliberately allowed the French to capture his regiment's flag at the Battle of Waterloo.
A seventy-year-old cold case of cowardice in the face of the enemy leads Holmes to France on the trail of the missing Waterloo colour. In 'Angelique', the first of five traditional stories narrated by Doctor Watson and with an occasional wry twist, Holmes is incapacitated by fever, and he requires his fellow lodger Doctor Watson to act as his sleuthhound in a missing persons case. Watson is constrained by Holmes to procure, "raw facts, my dear fellow. Do not expend your energy in analysis: leave that to me."
Watson's investigation uncovers two separate, competing conspiracies, with each conspirator plotting the destruction of the other. 'The Waterloo Colour' has Holmes investigating a seventy-year-old mystery that has spawned at least one duel and has had two families at each others' throats for a generation. The story of 'The Benevolent and Virtuous Order of the Swamp Python' sees a Chinese secret society attempt to establish itself in South London and Holmes' use of the most modern technology to thwart them. In 'The Abominable Madame Ricoletti', the escape of a patient from the lunatic asylum at Broadmoor puts Holmes, Watson and Lestrade at terrible risk. In 'Amity Among Nations', Holmes must find the source of a leak of diplomatic secrets that might be a catalyst for war between Great Britain and the United States. Join Holmes and Watson in their adventures in London's Chinatown, on the murky Thames, in Paris and an obscure abbey on the French border with Belgium, and in the secret recesses of the Foreign Office.
