My assistant shook his head. "Utterly impossible," he said. "Sir John cannot leave town just now. He must be at the head of things; can't possibly be spared. I saw him this morning before I left; he had been working all night and was nearly dead. 'Explain my position to them,' he said; 'nothing but strict duty would keep me away from Plymouth to-day.' So, you see how it is, Mr. Mayor?"

"Oh, quite, quite! Well, I must be getting round to the Guildhall. You will march up your men at half-past one? Thank you."

The man in the silk hat, who I realized must be the Mayor of Plymouth, hurried away. I was left face to face with Muir Lockhart.

He stared at me, not offensively, but in such a way that he could not have missed a detail of my appearance; he always was an observant beggar. Then he passed by without a sign of recognition. Good! I reflected, if my own colleague, who saw me for several hours each day, did not know me, no one else would. It seemed a good omen, and I blessed Danjuro in my heart.

And what a splendid liar Muir Lockhart was! He knew that I had gone away on my own, and he hadn't the least idea in the world where I was! It was a temptation to discover myself, but I refrained.

I was very puzzled. What on earth was he doing here in uniform, and talking to the Mayor about? I hadn't a suspicion of the truth even then, and I had a curious sense of being out of things, forgotten and on the scrap-heap! The long drive had made me hungry and I thought about lunch. Before going into the coffee-room I wished to remove the stains of travel, so I went down the corridor to the lavatory.

When I entered a man in his shirt-sleeves was bending over one of the basins and sluicing himself with many splashes. As I was washing my own swarthy hands he emerged from a towel and gave me a casual glance.

It was Mr. Van Adams!

I could not repress a violent start, the thing was so sudden. What did this gathering of the clans mean? He noticed my movement at once, and looked at me with inquiry in his eyes. The lavatory was quite empty save for our two selves, and my decision was taken at once.

"Mr. Van Adams?" I asked.
