use of locks is to keep out sneak-thieves and compel the modern scientific educated burglar to make a noise. But making a noise isn't enough here, at night. This place with all its fabulous treasures must be guarded constantly, now, every hour, as if the front door were wide open."
The bars replaced and the window apparently locked as before, Craig devoted his efforts to examining the packing cases in the basement. As yet apparently nothing down there had been disturbed. But while rummaging about, from an angle formed behind one of the cases he drew forth a cane, to all appearances an ordinary Malacca walking-stick. He balanced it in his hand a moment, then shook his head.
"Too heavy for a Malacca," he ruminated. Then an idea seemed to occur to him. He gave the handle a twist. Sure enough, it came off, and as it did so a bright little light flashed up.
"Well, what do you think of that?" he exclaimed. "For a scientific dark-lantern that is the neatest thing I have ever seen. An electric light cane, with a little incandescent lamp and a battery hidden in it. This grows interesting. We must at last have found the cache of a real gentleman burglar such as Bertillon says exists only in books. I wonder if he has anything else hidden back here."
