Suddenly a memory came tapping at Billie’s mind.

“Is some one connected with it called ‘Tweedledum’?” she asked.

“Hush!” whispered Marie-Jeanne. “Look the other way. I knew it was dangerous.”

The two other girls turned their heads quickly to see what the matter was, but they only saw pedestrians hurrying over the bridge.

“Why,—what——” they began. But Marie-Jeanne was gone.

“Taking an afternoon walk?” asked a voice so close to them that they started guiltily.

But to their great relief, it was their old steamer friend, Telemac Kalisch.

“We came down to see London Bridge,” Billie answered, shaking hands with him. “And how are you and where are you going?”

“I am taking a little stroll. May I not walk with you to your lodgings?”

Piloting the two young girls through the mass of people, Telemac finally steered them into a quiet street and they made for home.
