“Archie.”

I knew from the tone it was the start of a speech, so I settled back. He went on:

“Now and then I receive the impression that you suspect me of neglecting this or that detail of our business. Ordinarily you are wrong, which is as it should be. In the labyrinth of any problem that confronts us, we must select the most promising paths; if we attempt to follow all at once we shall arrive nowhere. In any art — and I am an artist or nothing — one of the deepest secrets of excellence is a discerning elimination. Of course that is a truism.”

“Yes, sir.”

“Yes. Take the art of writing. I am, let us say, describing the actions of my hero rushing to greet his beloved, who has just entered the forest. He sprang up from the log on which he had been sitting, with his left foot forward; as he did so, one leg of his trousers fell properly into place but the other remained hitched up at the knee. He began running towards her, first his right foot, then his left, then his right again, then left, right, left, right, left, right... As you see, some of that can surely be left out — indeed, must be, if he is to accomplish his welcoming embrace in the same chapter. So the artist must leave out vastly more than he puts in, and one of his chief cares is to leave out nothing vital to his work.”

“Yes, sir.”

“You follow me. I assure you that the necessity I have just described is my constant concern when we are engaged in an enterprise. When you suspect me of neglect you are in a sense justified, for I do ignore great quantities of facts and impingements which might seem to another intelligence — let it go without characterization — to be of importance to our undertaking. But I should consider myself an inferior workman if I ignored a fact which the event proved actually to have significance. That is why I wish to make this apology to myself, thus publicly, in your hearing.”

I nodded. “I’m still hanging on. Apology for what?”

“For bad workmanship. It may prove not to have been disastrous, it may even turn out of no importance whatever. But sitting here this afternoon contemplating my glories and sifting out the sins, it occurred to me, and I need to ask you about it. You may remember that on Wednesday evening, sixty-five hours ago, you were describing for me the contents of Inspector Cramer’s bean.”

I grinned. “Yeah.”
