deduction, and cross-examination by apparently idle questions.  But to one and all of his interrogations I gave the retort courteous.  His pressing attentions did not escape the notice of my fellow-travellers within earshot.  Looking out of the corner of my eye I saw that they did not regard this questioning of myself as being so innocent as it appeared.  Many were apparently familiar with German methods of inter-espionage and they extended me silent warning, by sign, frown, and wink.

The raw youth disappeared and I forgot all about him.  But to my surprise five minutes later I saw him returning along the corridor accompanied by a military official whom he had evidently brought from the military carriage attached to the train.  They came straight up to me.  The youth pointing directly at me remarked,

“Here he is.  See!  There’s the camera on his back!”

The officer looked at the strap and turning me round caught sight of the camera case.  He nodded in acquiescence.

“And I saw him using it,” went on the youth triumphantly.  “He has been taking photographs of the bridges and sentries along the line!”

I was distinctly amused at this charge because it was absolutely untrue.  But I was somewhat impressed by the strange silence which had settled upon my fellow-travellers and the inscrutable look upon the officer’s face.  Something serious was evidently amiss.  I turned to the officer.

“The accusation is absurd.  Why!  Look at the windows!  They have been kept closed all the time according to the military orders.  And you could not take a photograph through the closed windows even if you wanted to.  They are too begrimed with dirt.”

The officer did not say a word but continued to eye me narrowly.

I began to feel uncomfortable before that piercing gaze, so I decided to floor the aspiring detective working so zealously for the Fatherland and to point out the danger of jumping at conclusions.  I turned to him: 

“You say you saw me taking photographs?”

“Yes, with that camera on your back.”

“You are quite sure?”

“Yes!”

I swung the case which had been so offensive to his eyes round to the front of me.

“Now I’ll ask you again.  You are quite certain you saw me taking photographs?”

“Ach!  I distinctly saw you take the camera out of the case, take the pictures, and then put it back again!” was his rejoinder given with great emphasis.

I did not attempt to argue any further.  I clicked the catch of the case.  The lid flew open.  Both the officer and the youth craned forward expectantly, to draw back, the officer giving vent to a smothered ejaculation.

The camera case was full of cigarettes.

Being a heavy smoker I had stocked myself with cigarettes with which I had filled the camera case.  I turned them out into my hands leaving the case empty.
