In secret

The case in question concerned a letter in a yellow envelope, which was dumped along with other incoming mail upon one of the many long tables where hundreds of women and scores of men sat opening and reading thousands of letters for the Bureau of P. C.—whatever that may mean.

Excerpt:

The evening was becoming one of the coldest ever recorded in New York. The thermometer had dropped to 8 degrees below zero and was still falling. Fifth Avenue glittered, sheathed in frost; traffic police on post stamped and swung their arms to keep from freezing; dry snow underfoot squeaked when trodden on; crossings were greasy with glare ice.

It was, also, one of those meatless, wheatless, heatless nights when the privation which had hitherto amused New York suddenly became an ugly menace. There was no coal to be had and only green wood. The poor quietly died, as usual; the well-to-do ventured a hod and a stick or two in open grates, or sat huddled under rugs over oil or electric stoves; or migrated to comfortable hotels. And bachelors took to their clubs. That is where Clifford Vaux went from his chilly bachelor lodgings. He fled in a taxi, buried cheek-deep in his fur collar, hating all cold, all coal companies, and all Kaisers.
