G.K. Chesterton 
The Incredulity of Father Brown [EPUB ebook] 

FATHER BROWN always regarded the case as the queerest example of the theory of an alibi: the theory by which it is maintained, in defiance of the mythological Irish bird, that it is impossible for anybody to be in two places at once. To begin with, James Byrne, being an Irish journalist, was perhaps the nearest approximation to the Irish bird. He came as near as anybody could to being in two places at once: for he was in two places at the opposite extremes of the social and political world within the space of twenty minutes. The first was in the Babylonian halls of the big hotel, which was the meeting place of the three commercial magnates concerned with arranging for a coal lock-out and denouncing it as a coal-strike, the second was in a curious tavern, having the facade of a grocery store, where met the more subterranean triumvirate of those who would have been very glad to turn the lock-out into a strike—and the strike into a revolution. The reporter passed to and fro between the three millionaires and the three Bolshevist leaders with the immunity of the modern herald or the new ambassador.
