"How about your servants?" I asked Mrs. Leggett.

"We've only one-Minnie Hershey, a Negress. She doesn't sleep here, and I'm sure she had nothing to do with it. She's been with us for nearly two years and I can vouch for her honesty."

I said I'd like to talk to Minnie, and Mrs. Leggett called her in. The servant was a small, wiry mulatto girl with the straight black hair and brown features of an Indian. She was very polite and very insistent that she had nothing to do with the theft of the diamonds and had known nothing about the burglary until she arrived at the house that morning. She gave me her home address, in San Francisco's darktown.

Leggett and his wife took me up to the laboratory, a large room that covered all but a small fifth of the third story. Charts hung between the windows on the whitewashed wall. The wooden floor was uncovered. An X-ray machine-or something similar-four or five smaller machines, a forge, a wide sink, a large zinc table, some smaller porcelain ones, stands, racks of glassware, siphon-shaped metal tanks-that sort of stuff filled most of the room.

The cabinet the diamonds had been taken from was a green-painted steel affair with six drawers all locking together. The second drawer from the top-the one the diamonds had been in-was open. Its edge was dented where a jimmy or chisel had been forced between it and the frame. The other drawers were still locked. Leggett said the forcing of the diamond drawer had jammed the locking mechanism so that he would have to get a mechanic to open the others.

We went downstairs, through a room where the mulatto was walking around behind a vacuum cleaner, and into the kitchen. The back door and its frame were marked much as the cabinet was, apparently by the same tool.

When I had finished looking at the door, I took the diamond out of my pocket and showed it to the Leggetts, asking: "Is this one of them?"

Leggett picked it out of my palm with forefinger and thumb, held it up to the light, turned it from side to side, and said: "Yes. It has that cloudy spot down at the culet. Where did you get it?"

"Out front, in the grass."

"Ah, our burglar dropped some of his spoils in his haste."

I said I doubted it.

Leggett pulled his brows together behind his glasses, looked at me with smaller eyes, and asked sharply: "What do you think?"

"I think it was planted there. Your burglar knew too much. He knew which drawer to go to. He didn't waste time on anything else. Detectives always say: 'Inside job,' because it saves work if they can find a victim right on the scene; but I can't see anything else here."

Minnie came to the door, still holding the vacuum cleaner, and began to cry that she was an honest girl, and nobody had any right to accuse her of anything, and they could search her and her home if they wanted to, and just because she was a colored girl was no reason, and so on and so on; and not all of it could be made out, because the vacuum cleaner was still humming in her hand and she sobbed while she talked. Tears ran down her cheeks.

Mrs. Leggett went to her, patted her shoulder, and said: "There, there. Don't cry, Minnie. I know you hadn't anything to do with it, and so does everybody else. There, there." Presently she got the girl's tears turned off and sent her upstairs.

Leggett sat on a corner of the kitchen table and asked: "You suspect someone in this house?"

"Somebody who's been in it, yeah."

"Whom?"

"Nobody yet."

"That"-he smiled, showing white teeth almost as small as his daughter's-"means everybody-all of us?"

"Let's take a look at the lawn," I suggested. "If we find any more diamonds I'll say maybe I'm mistaken about the inside angle."

Half-way through the house, as we went towards the front door, we met Minnie Hershey in a tan coat and violet hat, coming to say good-bye to her mistress. She wouldn't, she said tearfully, work anywhere where anybody thought she had stolen anything. She was just as honest as anybody else, and more than some, and just as much entitled to respect, and if she couldn't get it one place she could another, because she knew places where people wouldn't accuse her of stealing things after she had worked for them for two long years without ever taking so much as a slice of bread.

Mrs. Leggett pleaded with her, reasoned with her, scolded her, and commanded her, but none of it was any good. The brown girl's mind was made up, and away she went.

Mrs. Leggett looked at me, making her pleasant face as severe as she could, and said reprovingly: "Now see what you've done."

I said I was sorry, and her husband and I went out to examine the lawn. We didn't find any more diamonds.

I put in a couple of hours canvassing the neighborhood, trying to place the man Mrs. and Miss Leggett had seen. I didn't have any luck with that one, bnt I picked up news of another. A Mrs. Priestly-a pale semi-invalid who lived three doors below the Leggetts-gave me the first line on him.

Mrs. Priestly often sat at a front window at night when she couldn't sleep. On two of these nights she had seen the man. She said he was a tall man, and young, she thought, and he walked with his head thrust forward. The street was too poorly lighted for her to describe his coloring and clothes.

She had first seen him a week before. He had passed up and down on the other side of the street five or six times, at intervals of fifteen or twenty minutes, with his face turned as if watching something-or looking for something-on Mrs. Priestly's-and the Leggetts'-side of the street. She thought it was between eleven and twelve o'clock that she had seen him the first time that night, and around one o'clock the last. Several nights later-Saturday-she had seen him again, not walking this time, but standing on the corner below, looking up the street, at about midnight. He went away after half an hour, and she had not seen him again.

Mrs. Priestly knew the Leggetts by sight, but knew very little about them, except that the daughter was said to be a bit wild. They seemed to be nice people, but kept to themselves. He had moved into the house in 1921, alone except for the housekeeper-a Mrs. Begg, who, Mrs. Priestly understood, was now with a family named Freemander in Berkeley. Mrs. Leggett and Gabrielle had not come to live with Leggett until 1923.

Mrs. Priestly said she had not been at her window the previous night and therefore had not seen the man Mrs. Leggett had seen on the corner.

A man named Warren Daley, who lived on the opposite side of the street, down near the corner where Mrs. Priestly had seen her man, had, when locking up the house Sunday night, surprised a man-apparently the same man-in the vestibule. Daley was not at home when I called, but, after telling me this much, Mrs. Daley got him on the phone for me.

Daley said the man had been standing in the vestibule, either hiding from or watching someone up the street. As soon as Daley opened the door, the man ran away, down the street, paying no attention to Daley's "What are you doing there?" Daley said he was a man of thirty-two or three, fairly well dressed in dark clothes, and had a long, thin, and sharp nose.

That was all I could shake the neighborhood down for. I went to the Montgomery Street offices of Spear, Camp and Duffy and asked for Eric Collinson.

He was young, blond, tall, broad, sunburned, and dressy, with the good-looking unintelligent face of one who would know everything about polo, or shooting, or flying, or something of that sort-maybe even two things of that sort-but not much about anything else. We sat on a fatted leather seat in the customers' room, now, after market hours, empty except for a weedy boy juggling numbers on the board. I told Collinson about the burglary and asked him about the man he and Miss Leggett had seen Saturday night.
