To Max, the great campaign he had in mind against Schenk and the Germans was momentarily eclipsed by the urgent need for doing something to relieve the distress of his mother and sister. He tried at first to think of friends, who, knowing the value of their property, might be disposed to advance a sufficient sum of money upon its security. It was in the midst of these reflections, and the angry thoughts of Schenk that naturally coloured them, that a wild and desperate idea occurred to him. He dismissed it at first as an absurdity, but the thought kept coming back again, until, weary of resisting it, he allowed his mind to dwell upon it at will. It was while heedlessly immersed in these rambling thoughts that a sudden recollection came which considerably altered the aspect of affairs. From a wild and desperate dream it changed into a project, difficult and perilous indeed, but one by no means hopeless of achievement. In the end it took such firm hold upon him that he thought it out seriously and at last unfolded it to Dale.

That worthy welcomed it with such unbounded admiration and delight that the question as to whether it should or should not be attempted was settled out of hand, and the preparations for carrying it into effect promptly begun.

The project was, briefly, to go and take by a coup de main the moneys belonging to his mother that Schenk had wrongfully and treacherously refused to hand over. It seemed a most risky venture, but Max had a recollection that his father long ago had entrusted to his mother the duplicate key of his safe in case anything should at any time happen to him. It had never been used, and his mother, likely enough, had almost forgotten she possessed it. Nevertheless, Max believed it was still in her possession, and he resolved to settle the point by sending a messenger to fetch it. More important still, he believed that Schenk was quite unaware of its existence. If the key could be secured it would simplify matters immensely, and, as Max was naturally familiar with the building in which the manager's office was situated, the enterprise was one which seemed likely to succeed if resolutely attempted. The safe, he knew, ought to contain all the money and securities of the firm, unless, indeed, Schenk had already handed them over to the Germans. This did not seem likely, however, and Max would not allow so disappointing a thought to interfere with his calculations.

Monsieur Dubec's eldest daughter was promptly dispatched to Madame Durend with a letter asking for the key. Max entered into no details, and his mother may possibly have supposed that M. Schenk's failure to send her the money he had promised was due to the loss of the original key. At any rate, to the delight both of Max and Dale, the key duly arrived the following day.

Tools were needed, and these were of course easily obtained. Max, as we have seen, had been through most of the shops in the Durend concern, and knew how to use almost any tool as well as the best of the firm's mechanics. No difficulties, therefore, were to be anticipated on that score. In fact, the more the details of the scheme were discussed the more feasible it seemed and the more the spirits of the two plotters rose.

The third night after the break with Schenk, Max and Dale set out from their lodging at midnight and made their way to the Durend workshops. Dale was carrying a good-sized bag, in which was a lantern and an assortment of tools and other articles, one or two of them of such a nature that to be stopped and the bag examined would have been fatal to their liberty of movement for many a long day. It was, therefore, necessary for them to move with caution, and Max accordingly went on a hundred yards ahead, ready to give the agreed signal—a stumble forward on the pavement—whenever it was advisable for Dale to disappear.

The offices of the Durend Company were situated in a separate building just inside the main entrance gates. The latter were ordinarily guarded by a watchman, but since the Germans had entered Liége a guard of German soldiers had been established there, and the sentinel on his beat passed within view of the front and two sides of the offices. It was pretty obvious, therefore, that the rear of the building would have to be the part attacked.

It was close on one o'clock when Max and Dale scaled the outer wall well away from the entrance, and moved cautiously up to the rear of the building which was their objective. They had had only one alarm so far, and this had been so easily disposed of that they had begun to feel quite elated.

"This window gives access to the drawing-office, Dale, and ought to suit us well. Give me a lift on to the sill, and hand up the tools."

In a surprisingly short space of time the window was forced open, and Max clambered into the room. A whispered word, and Dale handed up the bag and sprang quietly up after it.
