TO JOHN VINE MILNE MY DEAR FATHER,

Like all really nice people, you have a weakness for detective stories, and feel that there are not enough of them. So, after all that you have done for me, the least that I can do for you is to write you one. Here it is: with more gratitude and affection than I can well put down here.

A.A.M.

CHAPTER I

Mrs. Stevens is Frightened

In the drowsy heat of the summer afternoon the Red House was taking its siesta. There was a lazy murmur of bees in the flower-borders, a gentle cooing of pigeons in the tops of the elms. From distant lawns came the whir of a mowing-machine, that most restful of all country sounds; making ease the sweeter in that it is taken while others are working.

It was the hour when even those whose business it is to attend to the wants of others have a moment or two for themselves. In the housekeeper's room Audrey Stevens, the pretty parlour-maid, re-trimmed her best hat, and talked idly to her aunt, the cook-housekeeper of Mr. Mark Ablett's bachelor home.

"For Joe?" said Mrs. Stevens placidly, her eye on the hat. Audrey nodded. She took a pin from her mouth, found a place in the hat for it, and said, "He likes a bit of pink."

"I don't say I mind a bit of pink myself," said her aunt. "Joe Turner isn't the only one."

"It isn't everybody's colour," said Audrey, holding the hat out at arm's length, and regarding it thoughtfully. "Stylish, isn't it?"

"Oh, it'll suit you all right, and it would have suited me at your age. A bit too dressy for me now, though wearing better than some other people, I daresay. I was never the one to pretend to be what I wasn't. If I'm fifty-five, I'm fifty-five --that's what I say."

"Fifty-eight, isn't it, auntie?"

"I was just giving that as an example," said Mrs. Stevens with great dignity.

Audrey threaded a needle, held her hand out and looked at her nails critically for a moment, and then began to sew.

"Funny thing that about Mr. Mark's brother. Fancy not seeing your brother for fifteen years." She gave a self-conscious laugh and went on, "Wonder what I should do if I didn't see Joe for fifteen years."

"As I told you all this morning," said her aunt, "I've been here five years, and never heard of a brother. I could say that before everybody if I was going to die to-morrow. There's been no brother here while I've been here."

"You could have knocked me down with a feather when he spoke about him at breakfast this morning. I didn't hear what went before, naturally, but they was all talking about the brother when I went in--now what was it I went in for--hot milk, was it, or toast?--well, they was all talking, and Mr. Mark turns to me, and says--you know his way--'Stevens,' he says, 'my brother is coming to see me this afternoon; I'm expecting him about three,' he says. 'Show him into the office,' he says, just like that. 'Yes, sir,' I says quite quietly, but I was never so surprised in my life, not knowing he had a brother.
