There was no immediate alarm, but when the men again assembled at one o'clock for the grooming of the horses, which went on every afternoon from one to two o'clock, Jean's absence could not fail to be noticed. The whole length of the wall outside the stables, horses tethered to iron rings were being brushed down by men, amongst whom were the volunteers receiving a lesson in the art. The sergeants looked on nonchalantly when the _wachtmeister_ of the 3rd Company came out of his office, and made his way to the south side of the court, where Oberlé should have been. He bit his red moustache as his eyes wandered up and down the ranks. "Oberlé has not come back?" he asked. The same man as before replied: "When he left the barracks he ran towards his apartments." "Did you see him in the mess-room?" "He did not lunch with us." "That'll do," said the _wachtmeister_. Hamm turned away briskly. The expression of his face and eyes showed that he considered the situation serious. Serious for Oberlé, but equally serious for himself. Neither the captain nor the lieutenant was in barracks at the moment. If there was trouble the captain would not fail to ask why he had not been warned. Hamm crossed the courtyard, thinking over what he ought to do, and recalling a remark of the brigadier of Obernai. When Gottfried was at Obernai a fortnight before, he had said to him: "You are going to have Oberlé's son in your regiment. Keep an eye on him. I shall be surprised if he does not create some disturbance. He is the counterpart of his grandfather, a madman who hates Germans, and who is quite capable of any folly." But before taking zealous action it was necessary to know some details. This was easy: the rue des Balayeurs faced the gateway. Hamm brushed his blue tunic with his hand, left the barracks, and made his way to a large house on the left with green shutters. "Left in a cab, before midday, carrying a bag," was the answer Jean's landlady gave him. "What address did he give?" "Rue de la Mésange." "Any number?" "I don't know; anyway I heard none." Hamm's suspicions became more definite. The _wachtmeister_ no longer hesitated. He hastened to the captain's quarters in the Herderstrasse. The captain was out. Disappointed and warm from his sharp walk, Hamm took a short cut to the barracks, through the University gardens. He suddenly remembered that close by in the rue Grandidier, lived Lieutenant Farnow. It is true the lieutenant did not belong to the 2nd squadron, but Hamm knew of his engagement. It had been talked of among the officers. He made his way to the superb stone house and mounted to the first floor. "The lieutenant is dressing," replied the orderly to his question.
