They parted at the entrance of the bureau, Saul Arthur Mann returning to telephone the necessary instructions. How necessary they were was proved that very night. At nine o'clock May was sitting down to a solitary dinner when a telegram was delivered to her. It was from the chief of the little mission in which she had been interested, and ran: Very urgent. Have something of the greatest importance to tell you. It was signed with the name of the matron of the mission, and, leaving her dinner untouched, May only delayed long enough to change her dress before she was speeding in a taxi eastward. She arrived at the "hall," which was the headquarters of the mission, to find it in darkness. A man who was evidently a new helper was waiting in the doorway and addressed her. "You are Miss Nuttall, aren't you? I thought so. The matron has gone down to Silvers Rents, and she asked me to go along with you." The girl dismissed the taxi, and in company with her guide threaded the narrow tangle of streets between the mission and Silvers Rents. She was halfway along one of the ill-lighted thoroughfares when she noticed that drawn up by the side of the road was a big, handsome motor car, and she wondered what had brought this evidence of luxurious living to the mean streets of Canning Town. She was not left in doubt very long, for as she came up to the lights and was shielding her eyes from their glare her arms were tightly grasped, a shawl was thrown over her head, and she was lifted and thrust into the car's interior. A hand gripped her throat. "You scream and I will kill you!" hissed a voice in her ear. At that moment the car started, and the girl, with a scream which was strangled in her throat, fell swooning back on the seat. May recovered consciousness to find the car still rushing forward in the dark and the hand of her captor still resting at her throat. "You be a sensible girl," said a muffled voice, "and do as you're told and no harm will come to you." It was too dark to see his face, and it was evident that even if there were light the face was so well concealed that she could not recognize the speaker. Then she remembered that this man, who had acted as her guide, had been careful to keep in the shadow of whatever light there was while he was conducting her, as he said, to the matron. "Where are you taking me?" she asked. "You'll know in time," was the noncommittal answer. It was a wild night; rain splashed against the windows of the car, and she could hear the wind howling above the noise of the engines. They were evidently going into the country, for now and again, by the light of the headlamps, she glimpsed hedges and trees which flashed past. Her captor suddenly let down one of the windows and leaned out, giving some instructions to the driver. What they were she guessed, for the lights were suddenly switched off and the car ran in darkness.
