Now my luck again greatly favoured me. Just as I put my foot upon the bridge I saw a figure approaching me, coming from the opposite direction.

I recognized it instantly. It was the lady herself.

She must have seen me at the very same moment, for she halted dead with the abruptness of one faced with a sudden danger, an opened precipice, or a venomous snake under foot. She looked hurriedly to right and left, as if seeking some loophole of escape.

At that moment one of the many electric trams that overspread Geneva with a network of lines came swinging down the Rue de Mont Blanc from the Cornavin station, and slackened speed at the end of the bridge. My lady made up her mind then and there, and as it paused she boarded it with one quick, agile spring.

With no less prompt decision I followed her, and we entered the car almost simultaneously.

There were only two seats vacant and, curiously enough, face to face. I took my place, not ill pleased, for she had already seen me, and I was anxious to know how my sudden reappearance would affect her. It was clear she did not relish it, or she would not have turned tail at our unexpected meeting.

I had not long to wait. She chose her line at once, and without hesitation addressed me, smiling and unabashed. Her self-possession, I had almost said her effrontery, took me quite aback.

"Surely I am not mistaken?" she began quite coolly. "Have I not to thank you for your courtesy in the train a couple of days ago?"

I stammered a halting affirmative.
