With the reception of that telegram a light burst upon my mind. A doubt which I had tried in vain to stifle had vexed me all along as to the sufficiency of the Empress’s motive for retaining my services, at a high cost, to do practically nothing.

Now at last it seemed to me that I understood. This extraordinary woman had doubtless consulted her representatives in Europe as to the dangers of detection, and they had informed her that I was Wilhelm II.’s favourite confidential agent, who would almost certainly be called in if any suspicion arose. Thereupon she had adopted the artful device of retaining me on her own side in advance, placing me in the extremely delicate position of being bound by loyalty to her to hoodwink my other patron.

What was I to do? A bare refusal or neglect to answer the Kaiser’s summons would leave him free to employ another agent, whom I might find it hard to outwit. On the other hand, I should violate my lifelong rule, if I accepted a commission which I could not loyally discharge.

After much painful thought, I decided on what seemed to me the only wise and honourable course. Disguised as I was, I went straight round to the palace, and asked to see the Kaiser.

‘Impossible!’ declared the private secretary on duty, to whom I was first shown in. ‘His Majesty is retiring. Who are you?’

‘Go and tell the Emperor that the man whom he has just telegraphed to Paris for is here.’

The secretary gave me an astonished look, as he well might, and left the room.

In a minute he was back with instructions to conduct me to the Kaiser’s presence.

I found his Majesty in his dressing-room alone.

‘Monsieur V——! Is this really you?’ he exclaimed.
