Was it ignorance or something else that caused Dr. Brady to prescribe the wrong medicine for your daughter? Ask Bess Huddleston. She can tell you if she will. She told me.

There was no signature. I handed the sheet and envelope back to Wolfe.

Bess Huddleston used her handkerchief on her forehead and throat again. “There was another one,” she said, looking at Wolfe but her eyes making me feel she was looking at me, “but I haven’t got it. That one, as you see, is postmarked Tuesday, August 12th, six days ago. The other one was mailed a day earlier, Monday, the 11th, a week ago today. Typewritten, just like that. I’ve seen it. It was sent to a very rich and prominent man, and it said — I’ll repeat it. It said: ‘Where and with whom does your wife spend most of her afternoons? If you knew you would be surprised. My authority for this is Bess Huddleston. Ask her.’ The man showed it to me. His wife is one of my best—”

“Please.” Wolfe wiggled a finger at her. “Are you consulting me or hiring me?”

“I’m hiring you. To find out who sent those things.”

“It’s a mean kind of a job. Often next to impossible. Nothing but greed could induce me to tackle it.”

“Certainly.” Bess Huddleston nodded impatiently. “I know how to charge too. I expect to get soaked. But where will I be if this isn’t stopped and stopped quick?”

“Very well. Archie, your notebook.”

I got it out and got busy. She reeled it off to me while Wolfe rang for beer and then leaned back and closed his eyes. But he opened one of them halfway when he heard her telling me about the stationery and the typewriter. The paper and envelopes of both the anonymous letters, she said, were the kind used for personal correspondence by a girl who worked for her as her assistant in party-arranging, named Janet Nichols; and the letters and envelopes had been typed on a typewriter that belonged to Bess Huddleston herself which was used by another girl who worked for her as her secretary, named Maryella Timms. Bess Huddleston had done no comparing with a magnifying glass, but it looked like the work of that typewriter. Both girls lived with her in her house at Riverdale, and there was a large box of that stationery in Janet Nichols’ room.

Then if not one of the girls — one of the girls? Wolfe muttered, “Facts, Archie.” Servants? No use to bother about the servants, Bess Huddleston said; no servant ever stayed with her long enough to develop a grudge. I passed it with a nod having read about the alligators and bears and other disturbing elements in newspaper and magazine pieces. Did anyone else live in the house? Yes, a nephew, Lawrence Huddleston, also on the payroll as an assistant party-arranger, but, according to Aunt Bess, not on any account to be suspected. That all? Yes. Any persons sufficiently intimate with the household to have had access to the typewriter and Janet Nichols’ stationery?
