Would you believe it? I have letters which oblige me to go to Switzerland immediately. Messages, documents, anything--I could have taken them all to Defresnier and Rolland for you."

"You are the very man I wanted," returned Vendale. "I had decided, most unwillingly, on going to Neuchatel myself, not five minutes since, because I could find no one here capable of taking my place. Let me look at the letter again."

He opened the strong room to get at the letter. Obenreizer, after first glancing round him to make sure that they were alone, followed a step or two and waited, measuring Vendale with his eye. Vendale was the tallest man, and unmistakably the strongest man also of the two. Obenreizer turned away, and warmed himself at the fire.

Meanwhile, Vendale read the last paragraph in the letter for the third time. There was the plain warning--there was the closing sentence, which insisted on a literal interpretation of it. The hand, which was leading Vendale in the dark, led him on that condition only. A large sum was at stake: a terrible suspicion remained to be verified. If he acted on his own responsibility, and if anything happened to defeat the object in view, who would be blamed? As a man of business, Vendale had but one course to follow. He locked the letter up again.

"It is most annoying," he said to Obenreizer--"it is a piece of forgetfulness on Monsieur Rolland's part which puts me to serious inconvenience, and places me in an absurdly false position towards you. What am I to do? I am acting in a very serious matter, and acting entirely in the dark. I have no choice but to be guided, not by the spirit, but by the letter of my instructions. You understand me, I am sure? You know, if I had not been fettered in this way, how gladly I should have accepted your services?"

"Say no more!" returned Obenreizer. "In your place I should have done the same. My good friend, I take no offence. I thank you for your compliment. We shall be travelling companions, at any rate," added Obenreizer. "You go, as I go, at once?"

"At once. I must speak to Marguerite first, of course!"

"Surely! surely! Speak to her this evening. Come, and pick me up on the way to the station. We go together by the mail train to- night?"

"By the mail train to-night."

It was later than Vendale had anticipated when he drove up to the house in Soho Square. Business difficulties, occasioned by his sudden departure, had presented themselves by dozens. A cruelly large share of the time which he had hoped to devote to Marguerite had been claimed by duties at his office which it was impossible to neglect.

To his surprise and delight, she was alone in the drawing-room when he entered it.

"We have only a few minutes, George," she said. "But Madame Dor has been good to me--and we can have those few minutes alone." She threw her arms round his neck, and whispered eagerly, "Have you done anything to offend Mr. Obenreizer?"

"I!" exclaimed Vendale, in amazement.

"Hush!" she said, "I want to whisper it. You know the little photograph I have got of you. This afternoon it happened to be on the chimney-piece. He took it up and looked at it--and I saw his face in the glass. I know you have offended him! He is merciless; he is revengeful; he is as secret as the grave. Don't go with him, George--don't go with him!"

"My own love," returned Vendale, "you are letting your fancy frighten you! Obenreizer and I were never better friends than we are at this moment."

Before a word more could be said, the sudden movement of some ponderous body shook the floor of the next room. The shock was followed by the appearance of Madame Dor. "Obenreizer" exclaimed this excellent person in a whisper, and plumped down instantly in her regular place by the stove.

Obenreizer came in with a courier's big strapped over his shoulder. "Are you ready?" he asked, addressing Vendale. "Can I take anything for you? You have no travelling-bag. I have got one. Here is the compartment for papers, open at your service."

"Thank you," said Vendale. "I have only one paper of importance with me; and that paper I am bound to take charge of myself. Here it is," he added, touching the breast-pocket of his coat, "and here it must remain till we get to Neuchatel."

As he said those words, Marguerite's hand caught his, and pressed it significantly. She was looking towards Obenreizer. Before Vendale could look, in his turn, Obenreizer had wheeled round, and was taking leave of Madame Dor.

"Adieu, my charming niece!" he said, turning to Marguerite next. "En route, my friend, for Neuchatel!" He tapped Vendale lightly over the breast-pocket of his coat and led the way to the door.

Vendale's last look was for Marguerite. Marguerite's last words to him were, "Don't go!"

ACT III--IN THE VALLEY

It was about the middle of the month of February when Vendale and Obenreizer set forth on their expedition. The winter being a hard one, the time was bad for travellers. So bad was it that these two travellers, coming to Strasbourg, found its great inns almost empty. And even the few people they did encounter in that city, who had started from England or from Paris on business journeys towards the interior of Switzerland, were turning back.

Many of the railroads in Switzerland that tourists pass easily enough now, were almost or quite impracticable then. Some were not begun; more were not completed. On such as were open, there were still large gaps of old road where communication in the winter season was often stopped; on others, there were weak points where the new work was not safe, either under conditions of severe frost, or of rapid thaw. The running of trains on this last class was not to be counted on in the worst time of the year, was contingent upon weather, or was wholly abandoned through the months considered the most dangerous.

At Strasbourg there were more travellers' stories afloat, respecting the difficulties of the way further on, than there were travellers to relate them. Many of these tales were as wild as usual; but the more modestly marvellous did derive some colour from the circumstance that people were indisputably turning back. However, as the road to Basle was open, Vendale's resolution to push on was in no wise disturbed. Obenreizer's resolution was necessarily Vendale's, seeing that he stood at bay thus desperately: He must be ruined, or must destroy the evidence that Vendale carried about him, even if he destroyed Vendale with it.

The state of mind of each of these two fellow-travellers towards the other was this. Obenreizer, encircled by impending ruin through Vendale's quickness of action, and seeing the circle narrowed every hour by Vendale's energy, hated him with the animosity of a fierce cunning lower animal. He had always had instinctive movements in his breast against him; perhaps, because of that old sore of gentleman and peasant; perhaps, because of the openness of his nature, perhaps, because of his better looks; perhaps, because of his success with Marguerite; perhaps, on all those grounds, the two last not the least.
