to seize the opportunity so presented. Thank God you understood the cipher. If you love me give out that you proceed immediately to Egypt. Then go to Paris and return to London under another name and well disguised. Take lodgings East; and wait until you see in Personal Column of _Daily Wire_ directions addressed to 'D. Menchikoff!' Follow them implicitly! Am in power of fiends. Open opposition perilous. Must allay suspicion. Otherwise forced immediate marriage B." Here the missive ended. I sat down before the fire and thought hard for some minutes. The paper was crunched up in my hand. Suddenly the door opened. I turned my head at the sound of the creak, but could see no one. What could have opened the door? I heard the sound of caught breath, a foot on the door and a sigh. In a flash I understood. I had been seen by my enemies picking up the letter in the street, and they had sent their invisible messenger to win it from me. Quick as thought I thrust the paper in the flames and sprang afoot. There followed a deep-voiced oath and a rush of air fanned my face. I struck out with all my strength right and left, half beside myself with rage and fear. But my blows encountered nothing tangible, and a second later the door banged shut. I was so unnerved that I simply walked over and locked it. How can a man fight with an enemy he cannot see? or even follow him? When my hands stopped shaking I began to pack up my trunks. I resolved to follow Miss Ottley's bidding to the letter. To-morrow I would announce my departure for Egypt and cross the Channel in order to put Belleville off the track. Meanwhile I ransacked my wardrobe. Presently I received a shock. From an unremembered corner in a chest I brought out the clothes I had worn on the day of poor Weldon's death. They were covered with dyed bloodstains, the blood of my dead friend. I placed them on the table and eyed them, shuddering. My mind, as if spell-compelled, reviewed all the details of Weldon's death. I saw him stagger back, back, and fall beneath the wheels of the onrushing locomotive. I heard his dying shriek. Once more I struggled desperately, but alas! how vainly with the dark angel, for his life. Once more, as the end approached, I saw his glazed eyes open and look into mine. Once more I heard his dying words--"Give me your hand!" And but--God in Heaven! How could I ever have forgotten it! Had he not given me something--something I had put in my pocket half unconsciously without looking to see what it was--something he had implored me to "keep safe."
