man's handkerchief."

"It is," replied Ferguson. "And embroidered in one corner is the initial
'B.'"

Penfield ran his fingers through his gray hair. "You may go, Ferguson,"
he said, and beckoned to the morgue master. "Ask Miss Barbara McIntyre
to return."

The girl was quick in answering the summons. Kent, more and more
worried, was watching the scene with painful attention.

"Did Mr. Turnbull have one of your handkerchiefs?" asked Penfield.

Her surprise at the question was manifest in her manner.

"He might have," she said. "I have a dreadful habit of dropping my
handkerchiefs around."

"Did you miss one after his visit to your house on Monday night?"

"Miss McIntyre," Penfield took up the handkerchief which the foreman
replaced on his desk a moment before, and holding it with care extended
it toward the girl. "Is this your handkerchief?"

She inspected the handkerchief and the initial with curiosity, but with
nothing more, Kent was convinced, and in his relief was almost guilty of
disturbing the decorum of the inquest with a shout of joy.

"It is not my handkerchief," she stated clearly.

Penfield replaced the handkerchief on the table with the same care he
had picked it up, and turned again to her.

"Thank you, Miss McIntyre; I won't detain you longer. Logan," to the
morgue master, "ask Dr. Stone to step here."

Almost immediately Stone reentered the room and hurried to the platform.

"Would two or more capsules of amyl nitrite constitute a lethal dose?"
asked Penfield.

"They would be very apt to finish a feeble heart," replied Stone. "Three
capsules, if inhaled deeply would certainly kill a healthy person."

Penfield showed the handkerchief to the physician. "Can a chemist tell,
from the particles clinging to this handkerchief, how many capsules have
been used?"

"I should say he could." Stone looked grave as he inspected the linen,
taking careful note of the letter "B" in one corner of the handkerchief.
"But there is this to be considered--Turnbull may not have crushed those
capsules all at the same time."

"What do you mean?"

"He may have felt an attack coming on earlier in the evening and used a
capsule, and in the police court used the same handkerchief in the same
manner."

"I see," Penfield nodded. "The point is cleverly taken."

Kent silently agreed with the coroner. The next instant Stone was
excused, and after a slight pause the deputy coroner, Dr. Mayo, left his
table and his
