Martin Hewitt seemed singularly excited. "See there," he said, "that is how Denson left the building without passing the housekeeper's box! And now I'm going to make another shot. See here. This key on Denson's bunch attracted my attention because of its noticeable newness compared with most of the others. Most of the others, I say, because there is one other just as bright—see!

Hutt turned the key over in his hand and glanced from it to his own bunch. "Why, yes, sir!" he said presently. "Yes, sir! It's the same as the key of the fire-hose cupboards!"

"Does that key fit them all? How many firehose cupboards are there?"

"Two on each floor, sir, one at each end, just against the mains. And one key fits the lot."

"Show us the nearest to this door."

A short, narrow passage led to the main ground-floor corridor, where a cupboard lettered "Fire Hose" stood next the main and its fittings. "We have to keep the hose-cupboards locked," the housekeeper explained apologetically, "'cause o' mischievous boys in the offices."
