ossibly she had seen the significant
gesture with which the Curator pointed out a quiver from which one of the
arrows was missing. That this was so, was shown by her next question:

"But where is the bow? Look about on the floor. You will find none. How
can an arrow be shot without a bow?"

"It cannot be," came from some one at her back. "But it can be driven
home like a dagger if the hand wielding it is sufficiently powerful."

A cry left her lips; she seemed to listen as for some echo; then in a
wild abandonment which ignored person and place she flung herself again
at the dead girl's side, and before the astonished people surrounding her
could intervene, she had caught up the body in her arms, and bending over
it, whispered word after word into the poor child's closed ear.

IN ROOM B

Five minutes later the Curator was at the 'phone calling up Police
Headquarters. A death had occurred at the museum. Would they send over
a capable detective?

"What kind of death?" was the harsh reply. "We don't send detectives in
cases of heart-failure or simple accident. Is it an accident?"

"No--no--hardly. It looks more like an insane woman's attack upon a

A muffled sound at the other end--then a different voice asking some
half-dozen comprehensive questions--which, having been answered to the
best of the Curator's ability, were followed by the welcome assurance
that a man on whose experience he could rely would be at the museum doors
within five minutes.

With an air of relief Mr. Jewett stepped again into the court, and
repelling with hasty gestures the importunities of the small group of men
and women who had lacked the courage to follow the more adventurous ones
upstairs, crossed to where the door-man stood on guard over the main
entrance.

"Locked?" he asked.

"Yes, sir. Such were the orders. Didn't you give them?"

"No, but I should have done so, had I known. No one's to go out, and no
one's to come in but the detective whom I am expecting any moment."

They had not long to wait. Before their suspense had reached fever-point,
a tap was heard on the great door. It was opened, and a young man stepped
in.

"Coast clear?" he sang out with a humorous twist of his jaw as he noted
the Curator's evident
