ef which greeted this simple
elucidation of the mystery were broken by a curiously choked, almost
unintelligible, cry. It came from the man thus appealed to, who,
unnoticed by them all, had started at her first word and gradually, as
action followed action, withdrawn himself till he now stood alone and in
an attitude almost of defiance behind the large table in the centre of
the library.

"I am sorry," he began, with a brusqueness which gradually toned
down into a forced urbanity as he beheld every eye fixed upon him in
amazement, "that circumstances forbid my being of assistance to you in
this unfortunate matter. If the paper lies where you say, and I see no
other explanation of its loss, I am afraid it will have to remain there
for this night at least. The cement in which that door is embedded
is thick as any wall; it would take men with pickaxes, possibly with
dynamite, to make a breach there wide enough for any one to reach in.
And we are far from any such help."

In the midst of the consternation caused by these words, the clock

stroke, but that meant two hours after midnight and had the effect of a
knell in the hearts of those most interested.

"But I am expected to give that formula into the hands of our manager

"The paper would not be the same. That would lead to questions and the
truth would come out. As the chief value of the process contained in
that formula lies in its secrecy, no explanation I could give would
relieve me from the suspicions which an acknowledgment of the existence
of a third copy, however well hidden, would entail. I should lose my
great opportunity."

Mr. Cornell's state of mind can be imagined. In an access of mingled
regret and despair, he cast a glance at Violet, who, with a nod of
understanding, left the little room in which they still stood, and
approached Mr. Van Broecklyn.

Lifting up her head,--for he was very tall,--and instinctively rising on
her toes the nearer to reach his ear, she asked in a cautious whisper:

"Is there no other way of reaching that place?"

She acknowledged afterwards, that for one moment her heart stood still
from fear, such a change took place in his face, though she says he
