"Yes, I believe they were at it yesterday afternoon. But come in--Dorcas is here."
"Eh bien, eh bien! Do not grudge me a moment's satisfaction of the eye."
"Yes, but this affair is more important."
"And how do you know that these fine begonias are not of equal importance?"
I shrugged my shoulders. There was really no arguing with him if he chose to take that line.
"You do not agree? But such things have been. Well, we will come in and interview the brave Dorcas."
Dorcas was standing in the boudoir, her hands folded in front of her, and her grey hair rose in stiff waves under her white cap. She was the very model and picture of a good old-fashioned servant.
In her attitude towards Poirot, she was inclined to be suspicious, but he soon broke down her defences. He drew forward a chair.
"Pray be seated, mademoiselle."
"Thank you, sir."
"You have been with your mistress many years, is it not so?"
"Ten years, sir."
"That is a long time, and very faithful service. You were much attached to her, were you not?"
"She was a very good mistress to me, sir."
"Then you will not object to answering a few questions. I put them to you with Mr. Cavendish's full approval."
"Oh, certainly, sir."
"Then I will begin by asking you about the events of yesterday afternoon. Your mistress had a quarrel?"
"Yes, sir. But I don't know that I ought----" Dorcas hesitated. Poirot looked at her keenly.
"My good Dorcas, it is necessary that I should know every detail of that quarrel as fully as possible. Do not think that you are betraying your mistress's secrets. Your mistress lies dead, and it is necessary that we should know all--if we are to avenge her. Nothing can bring her back to life, but we do hope, if there has been foul play, to bring the murderer to justice."
"Amen to that," said Dorcas fiercely. "And, naming no names, there's one in this house that none of us could ever abide! And an ill day it was when first he darkened the threshold."
Poirot waited for her indignation to subside, and then, resuming his business-like tone, he asked: "Now, as to this quarrel? What is the first you heard of it?"
"Well, sir, I happened to be going along the hall outside yesterday----"
"What time was that?"
