. Of course she might be in our employ, but I doubt it, although I
could not be expected to know by sight every girl who works in the
plant. There are stenographers, film cutters and pasters, dozens of
others, that I do not engage directly, and never see. Let me look at the
card."

Duvall handed the torn bit of pasteboard to him.

"Not much to go on," he said, quietly.

"No. Not much."

"Of course," the detective went on, "the evening has not been entirely
wasted. We know the woman by sight, and that is a great deal. As for her
name, I have made a careful study of this card, and assuming it to have
been of the usual length in comparison to its width, the name following
the 'Miss,' if it was a first name, points to a very short one, such as
Mary, and not a long one, such as Margaret."

"How do you make that out?"

"Simply enough. The entire name would of course have been placed in the
center of the card, which was, it appears, torn almost exactly in half.
On the left-hand side, which we have in our possession, there are, in
the word 'Miss,' four letters, and in 'Mar' three, or seven in all. We
should correspondingly expect to find seven letters on the right or
missing half of the card. But were the first name Margaret, or Marcella,
which each contain eight letters, or five to be added to the 'Mar' we
already have, it would leave but two letters for the woman's last name,
and names of that length, or rather shortness, are so rare as to be
negligible. It is far more probable that we have but to add a 'y' to the
'Mar,' or one letter, leaving six for the last name. This would give us
'Miss Mar-y Gordon,' with the name evenly divided by the tear. Or, if by
chance, the first name is such a one as Marian, containing six letters,
we need add but the 'ian,' or three letters, to the left-hand side of
our card, leaving us four letters for the last name. Thus, Miss Marian
Kent. The full name on the card should have just fourteen letters,
provided the card is, as I conclude, torn exactly in half."

"Why do you conclude that?"

"Because visiting cards of this sort are usually made in standard sizes.
I happen to have a woman's card--Miss Morton's, in fact, in my pocket.
Its width is the same as that of the torn card, and if the latter was of
the same length, you can readily see that it was torn exactly in half."
He took a card from his wallet and laid the torn bit of pasteboard upon
it. Their widths were identical. The whole c
