"But Hamish and Angus. Can she get on without them?"

"She intends to have them follow her by train, with luggage. She says she has a 'feeling in her bones' that they'll come in handy, either for cooking or fighting. And by Jove, she may be right. She often is. If you go to Biskra and wire when you get there, I'll start at once—we'll start, I mean. And if Maïeddine goes on anywhere else, and you follow to keep him in sight, I'll probably catch you up with the car, because the railway line ends at Biskra, you know; and beyond, there are only horses or camels."

"Can motors go farther?"

"They can to Touggourt—with 'deeficulty,' as the noble twins would say."

"Maïeddine may take a car."

"Not likely. Though there's just a chance he might get some European friend with a motor to give him a lift. In that case, you'd be rather stuck."

"Motor cars leave tracks," said Stephen.

"Especially in the desert, where they are quite conspicuous," Nevill agreed. "My aunt will be enchanted with your opinion of her and her plan—but not surprised. She thinks you've twice my sense and knowledge of the world."

Nevill usually enjoyed his own dinner-parties, for he was a born host, and knew that guests were happy in his house. That night, however, was an exception. He was absent-minded, and pulled his moustache, and saw beautiful things in the air over people's heads, so often that not only Lady MacGregor but Angus and Hamish glared at him threateningly. He then did his best to atone; nevertheless, for once he was delighted when every one had gone. At last he was able to read for the second time a letter from Roslin, sent in while dinner was in progress. There had been only time for a glance at it, by begging his friends' indulgence for an instant, while he bolted the news that Stephen had followed Maïeddine to Biskra. Now, Nevill and Lady MacGregor both hugely enjoyed the details given by Roslin from the report of an employé; how cleverly Monsieur had kept out of sight, though the Arab had walked up and down the platform, with two friends, looking about keenly. How, when Maïeddine was safely housed in his compartment, his companions looking up to his window for a last word, Monsieur Knight had whisked himself into a second-class compartment at the other end of the train.

Next day, about four o'clock, a telegram was brought to Djenan el Djouad. It came from Biskra, and said: "Arrived here. Not spotted. He went house of French commandant with no attempt at concealment. Am waiting. Will wire again soon as have news. Perhaps better not start till you hear."
