"I think," said Mr. Li, with a smile of triumph in his dark eyes, "they will find it a little difficult to break through that door. Now let us collect what we require for the journey."
"The packages are here," said Mr. St. John. "We have had them all placed in the corner of the room."
"That is well," replied Mr. Li. "Now we will continue our journey. It will take our friends some little time," he added, pleasantly, "to force an entrance into this room, and I think they will be more than ever puzzled when they get here. You see these four doors," he said, pointing to one side of the apartment which seemed to be composed entirely of doors, "Which do you think is the one to be used? They are all dummies," he continued, after a pause, in which the doors had been tried and various opinions expressed: "but I fancy they will puzzle our friends. The real one is here."
He touched a spring which was wholly invisible to any but the most practised eye, and they found themselves in a kind of hall, the walls of which were very lofty, the light entering by mere apologies for windows, let in close to the ceiling. There were low divans all round this hall, and Mr. Li begged them to be seated.
"We may as well rest here a few moments," he said, noticing Nina's white face. "We are safe for the present, at least."
At this moment Mr. Crawford crossed over to where Mr. Li was standing, and spoke in a low tone.
"I suppose," he said, "there is no danger from outside? I wonder they do not try and effect an entrance from without."
"They would find it a little difficult," replied Mr. Li. "No cat could climb these walls, and only a cat could get in at the windows. No, the danger does not lie here, but further on. From this room there is a subterranean passage about a quarter of a mile long, but unfortunately it has no communication with the rest of the house opposite; the exit being at the other end of the grove of plantains, under which it runs. I always intended to complete the work, but it has not been done, and the consequence is, we must risk getting across twenty yards of open country. For men it would not be so difficult, but the care of two ladies complicates matters. We must hope and pray that the men will be so occupied with getting into the house that they will not think of anything beyond. Still, we must prepare for emergencies. I shall lead the way, for I must open the door of the other house. The lock is a complicated one, and only I can turn the key. You and Mr. St. John will follow with the ladies. It will be as well to acquaint Mr. St. John also of the possible danger, without alarming the ladies. Ah, here he is."
"Brother," said Paul St. John, laying his hand on the other's arm, "what fills me with wonder is your great ingenuity. Surely you must have travelled a great deal, for I have never seen a house like this in China."
"No," replied Mr. Li, smiling; "I have travelled a great deal, and am very cosmopolitan in my tastes. When I was a boy I used to pore over Eastern tales of adventure, and I determined to build one of those wonderful fairy palaces one reads of: a place of concealed doors, sliding panels, and underground passages."
