Up and Down by E.F. Benson

Out of the serene stillness, and with the swiftness of the hurricane, the storm came up. It was in June that there appeared the little cloud, no bigger than a man's hand, when the heir to the Austrian throne was murdered at Serajevo. There it hung on the horizon, and none heeded, though in the womb of it lurked the seed of the most terrific tempest of blood and fire that the world has ever known. Suddenly in the last week of July that seed fructified, shooting out monstrous tendrils to East and West. A Note was sent from Vienna to Servia making demands, and insisting on terms that no State could possibly entertain, if it was henceforth to consider itself a free country. Servia appealed to Russia for protection, and Russia remonstrated with those who had framed or (more accurately) those who had sent that Note. The remonstrance fell on ears that had determined not to hear, and the throttling pressure of the inflexible hands was not abated.

London and Paris appealed for a conference, for arbitration that might find a peaceful solution, for already all Europe saw that here was a firebrand that might set the world aflame. And then we began to see who it was that had caused it to be lit and flung, and who it was that stood over it now, forbidding any to quench it.
