"I took it that the murder, if it was a murder, would be a sordid business, in keeping with Lord Loudwater himself.

But if you're going to introduce a lady into the case, it promises to be more fruitful in interest for the dramatist.

I'm writing plays." But Mr.Flexen was not going to divulge the curious fact that about the time of his murder Lord Loudwater had had a violent quarrel with a lady.
He had no doubt that Mrs.Carruthers would keep it to herself.
"Oh, one has to look out for every possible factor in a problem like this, you know," he said carelessly.
The faint frown lingered on Mr.Manley's brow.

Mr.Flexen supposed that it was the result of his refraining from gratifying his appetite for the dramatic.

They were silent a while.
"When are you going to take our finger-prints ?" said Mr.Manley presently.
"Not till I've learned whether there are any on the handle of the knife," said Mr.Flexen.
