There was no time to spare for further thought or conjecture concerning the mystery of the missing papers until, an hour and a half later, they were on their way to Victoria, whirling rapidly along in a taxi, for the fog had lifted.

They had none too much time to get the train to Dover, where they intended to stay the night at the “Lord Warden” and cross to Calais next day, en route for Paris and the Riviera.

“Same here! And it really is curious considering she’s always been so jolly decent to us both. I wonder——”

He broke off, knitting his brows perplexedly, and as if in response to his unspoken thought Grace exclaimed:

“No. And I don’t know what to think about Lady Rawson. Oh, bother the papers; let’s forget all about them—for to-day, anyhow! I say, beloved, it doesn’t seem possible that we’re really married and off on our honeymoon, does it?”
