I was attempting to discuss with him the sensational news of that day—no less than an attempted assassination of Mr. David MacAdam, England’s Prime Minister. The account in the papers had evidently been carefully censored. No details were given, save that the Prime Minister had had a marvellous escape, the bullet just grazing his cheek.

I considered that our police must have been shamefully careless for such an outrage to be possible. I could well understand that the German agents in England would be willing to risk much for such an achievement. “Fighting Mac,” as his own party had nicknamed him, had strenuously and unequivocally combated the Pacifist influence which was becoming so prevalent.

He was more than England’s Prime Minister—he was England; and to have removed him from his sphere of influence would have been a crushing and paralysing blow to Britain.

Poirot was busy mopping a grey suit with a minute sponge. Never was there a dandy such as Hercule Poirot. Neatness and order were his passion. Now, with the odour of benzine filling the air, he was quite unable to give me his full attention.

“In a little minute I am with you, my friend. I have all but finished. The spot of grease—he is not good—I remove him—so!” He waved his sponge.

I smiled as I lit another cigarette.

“Anything interesting on?” I inquired, after a minute or two.

“I assist a—how do you call it?—‘charlady’ to find her husband. A difficult affair, needing the tact. For I have a little idea that when he is found he will not be pleased. What would you? For my part, I sympathize with him. He was a man of discrimination to lose himself.”

I laughed.

“At last! The spot of grease, he is gone! I am at your disposal.”
