er's affairs. Pilar ingenuously hoped
that we might meet again in Madrid. The Duke said he hoped so too, but did
not know, as they were motoring, and stopped each day where fancy
prompted. Pilar thought this charming, and said that we were going to have
a little trip with an automobile, too. An American friend had invited us.

At that very moment the American friend was visible in the dim distance,
standing with his back to us, gazing at an alabaster tomb. One would have
thought he had some reason for avoiding us, or else escaping an
introduction to the others, for he let them leave the cathedral before he
tore himself away from his study of the sleeping cardinal. When they had
vanished, however, he came towards us with a briskness which showed that
he had taken more interest in our movements than he appeared to do.

"It's gone off beautifully!" Pilar informed him. "And you did exactly
right, Senor Waring. You see," she said to me, "on second thoughts one saw
he'd better keep out of the way, for fear the Duke might begin to put two
and two together, just as he was noticing that Cristobal looked rather
like someone else. He caught a glimpse of Senor Waring's face yesterday,
in the car, and it will be safer for him not to see _us_ in that car until
we have gone on a little further. Then, he will have had time to get used
to my brother's face, as my brother's. Wasn't that a clever idea of mine?"

We all praised her; and praised her again when she explained her policy in
having dropped a hint about our American motoring friend, so that she need
not be suspected of having tried to conceal anything when the car appeared
on the scene.

"The Duke's auto was at the door when I came in," said Dick. "He must have
seen ours."

"Yes. But he saw you, too, prowling round the cathedral by yourself. I
suppose you have as much right to be motoring in Spain as he has, seeing
the sights?"

This was true. And as the grey car had now probably gone off, it was time
that ours persued.

Ropes was in his seat, coated and legginged once more in leather, and so
well goggled that there was no reason why he should be associated in any
mind with that Mr. George Smith who had threatened to air his wrongs in
_The Times_. He had seen the other car go, so we must follow. We crossed
the Arlanzon and I looked back regretfully at the citadel of Burgos,
rising in the middle of the town. We had had no time to visit that castle
in which so much history
