“In the wash-stand drawer in Mrs. Inglethorp’s bedroom. It was Number Six of my catalogue.”
“But I suppose, as the last powder was taken two days ago, it is not of much importance?”
“Probably not, but do you notice anything that strikes you as peculiar about this box?”
I examined it closely.
“No, I can’t say that I do.”
“Look at the label.”
I read the label carefully: “‘One powder to be taken at bedtime, if required. Mrs. Inglethorp.’ No, I see nothing unusual.”
“Not the fact that there is no chemist’s name?”
“Ah!” I exclaimed. “To be sure, that is odd!”
“Have you ever known a chemist to send out a box like that, without his printed name?”
