"If you play me false."
"I have sworn it by my honoured ancestors. Have no fear. Rest here awhile. My servants will see to your needs whilst I am absent."
I was left alone in this strange underground nest of luxury. The second Chinese attendant had reappeared. One of them brought food and drink and offered it to me, but I waved them aside. I was sick—sick—at heart—
And then suddenly the master reappeared tall and stately in his silken robes. He directed operations. By his orders I was hustled back through the cellar and tunnel into the original house I had entered. There they took me into a ground floor room. The windows were shuttered, but one could see through the cracks into the street. An old ragged man was shuffling along the opposite side of the road, and when I saw him make a sign to the window, I understood that he was one of the gang on watch.
"It is well," said my Chinese friend. "Hercule Poirot has fallen into the trap. He approaches now—and alone except for the boy who guides him. Now, Captain Hastings, you have still one more part to play. Unless you show yourself he will not enter the house. When he arrives opposite, you must go out on the step and beckon him in."
"What?" I cried, revolted.
"You play that part alone. Remember the price of failure. If Hercule Poirot suspects anything is amiss and does not enter the house, your wife dies by the Seventy lingering Deaths! Ah! Here he is."
With a beating heart, and a feeling of deathly sickness, I looked through the crack in the shutters. In the figure walking along the opposite side of the street I recognised my friend at once, though his coat collar was turned up and an immense yellow muffler hid the bottom part of his face. But there was no mistaking that walk, and the poise of that egg-shaped head.
It was Poirot, coming to my aid in all good faith, suspecting nothing amiss. By his side ran a typical London urchin, grimy of face and ragged of apparel.
Poirot paused, looking across at the house, whilst the boy spoke to him eagerly and pointed. It was the time for me to act. I went out in the hall. At a sign from the tall Chinaman, one of the servants unlatched the door.
