"Did I omit any questions I should have asked?" the spy-student inquired after they had ridden a short distance.
"You did fine," Lieut. Osborne replied. "I couldn't think of another question that I would have asked."
CHAPTER XIX
LAST PREPARATIONS
The next move in Irving's program of preparation for spy work in Germany had to do with the tattooing of an altered copy of the cubist art message on his arm. The alterations were made by the cryptologist who had deciphered the original message. He made the changes after consulting with intelligence officials, who prepared a system of dots and dashes that ostensibly conveyed valuable information. This "information," however, was not only misleading, but it was of such character that the deception could hardly be discovered before the lapse of months and possibly a year or more.
By the time the spy-student had "completed his course of study" the material, instruments, and artist were ready for the pictorial operation. The instruments had been supplied by a surgeon, the artist had been discovered after a search by telephone communication with the various official headquarters of the regiment, and the material, some pure aniline dye, had been found in a moving laboratory, or automobile chemical outfit, maintained for surgical, sanitation, pure food, and pure water purposes for the army.
The artist, aided by a surgeon, and the dye and some sharp-pointed needles, did the work. It was a long and tedious task, and many rests were required for the users of the dye-dipped needles in order to keep their nerves steady and their judgment sure in the delicate workmanship. After it was finished, the boy compared it with the salt-preserved original, and decided that the result could hardly have been more satisfactory for the desired purpose.
Then Irving had another session with Col. Evans, who gave him his final instructions.
"I haven't given you much of an idea yet what we want you to find out for us at Berlin, or wherever you can get the information," said the commander of the regiment. "We know, of course, that there is an extensive enemy spy organization in both Canada and the United States, and while we are able to get a few of those fellows now and then, still they're pretty smart as a rule, and we feel that we have only scratched the surface. We want their names, or the name of every leader of consequence among them. That's what we're sending you into Germany for. You must realize, therefore, that the mission on which you are being sent is one of no small consequence. The highest officers in the army have been acquainted with the plan and not only concurred in it, but offered suggestions for its improvement and perfection.
"You have learned from Hessenburg what you are to do when you land on German soil. You will probably be taken to Berlin or some important German military point, and there your message will be read. You will be a hero in the minds of the highest commanders and will undoubtedly be granted any favor you ask. My suggestion is that you ask to be assigned for study to qualify you for the most confidential and important work in the enemy secret service. Tell them you wish to return to America as a leader in the work and call their attention to the fact that, as you have become pretty thoroughly Americanized, or Canadianized, and lost most of the foreign appearance and accent of your father, you can pass successfully as a loyal citizen of the dominion. Then work your way into the confidence of those who are directing the spy system of our enemies and get at their records. Get the names of all the leaders you can find. You may be able to do this openly, for your own information when you return to take up more important work in Canada and the United States. Give special attention to the spy activities in the United States, for we want to show that the pro-German agents in that country are violating its policy of neutrality.
