This meal was not for herself; for in the cupboard I have found the remains of her own dinner.

She had dined off fish; the autopsy will confirm the truth of this statement.

Besides you can see yourselves, there is but one glass on the table, and one knife.

But who is this young man?
Evidently the widow looked upon him as a man of superior rank to her own; for in the cupboard is a table-cloth still very clean.

Did she use it?
No.
