Her initial difficulty met her when she learned there were several sleeping cars on that train, and she was puzzled to know which to select.

She stood there, hesitating, with the plans of the carriages on the table before her.
"You have ample choice," said the clerk; "seats are not usually booked so long in advance, and only two places have been taken in the train, so far." "I should like to be in a carriage containing some English people," said the girl, not knowing what excuse to give for her hesitation.
"Then let me recommend this car, for one compartment has been taken by the British Embassy--Room C, near the centre, marked with a cross." "Ah, well, I will take the compartment next to it--Room D, isn't it ?" said Jennie.
"Oh, I am sorry to say that also has been taken.

Those are the two which are bespoken.

I will see under what name Room D has been booked.
Probably its occupant is English also.

But I can give you Room B, on the other side of the one reserved by the Embassy.
