ber this," said Mann, seriously, before they parted, "that if Cole
finds the game is up he will stop at nothing."

"Do you think we ought to take precautions?" asked Frank.

"Honestly I do," confessed the other, "I don't think we can get the men
from the Yard, but there is a very excellent agency which sometimes
works for me, and they can provide a guard for the girl."

"I wish you would get in touch with them," said Frank earnestly. "I am
worried sick over this business. She ought never to be left out of their
sight. I will see if I can have a talk to her maid, so that we may know
whenever she is going out. There ought to be a man on a motor cycle
always waiting about the Savoy to follow her wherever she goes."

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

"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
