out search. So I had that person shadowed, and at the
same time I had our telephone lines tapped, and eavesdropped on all
calls entering or leaving this center. And the person who had to be the
spy-courier called Adam Lowiewski, and Lowiewski made an appointment to
meet him at the Oppenheimer Village Recreation House to play chess."

"Very suspicious, very suspicious," Lowiewski derided. "I receive a call
from a friend at the same time that some anonymous suspect is using the
phone. There are only five hundred telephone conversations a minute on
this reservation."

"Immediately, Dr. Lowiewski attempted to leave this building," MacLeod
went on. "When I intercepted him, he tried to draw a pistol. This one."
He exhibited the Beretta. "I am now going to have Dr. Lowiewski
searched, in the presence of all of you." He nodded to Alex and the
Englishman.

They did their work thoroughly. A pile of Lowiewski's pocket effects was
made on the table; as each item was added to it, the Pole made some
sarcastic comment.

"And that pack of cigarettes: unopened," he jeered. "I suppose I
communicated the data to the manufacturers by telepathy, and they
printed it on the cigarette papers in invisible ink."

"Maybe not. Maybe you opened the pack, and then resealed it," Kato
suggested. "A heated spatula under the cellophane; like this."

He used the point of his knife to illustrate. The cellophane came
unsealed with surprising ease: so did the revenue stamp. He dumped out
the contents of the pack: sixteen cigarettes, four cigarette tip-ends,
four bits snapped from the other ends--and a small aluminum microfilm
capsule.

Lowiewski's face twitched. For an instant, he tried vainly to break
loose from the men who held him. Then he slumped into a chair. Heym
ben-Hillel gasped in shocked surprise. Suzanne Maillard gave a short,
felinelike cry. Sir Neville Lawton looked at the capsule curiously and
said: "Well, my sainted Aunt Agatha!"

"That's the capsule I gave him, at noon," Farida Khouroglu exclaimed,
picking it up. She opened it and pulled out a roll of colloidex
projection film. There was also a bit of cigarette paper in the capsule,
upon which a notation had been made in Kyrilic characters.

Rudolf von Heldenfeld could read Russian. "'Data on new development of
photon-neutrino-electron interchange. 22 July, '65. Vladmir.' Vladmir, I
suppose, is this _schweinhund's_ code name," he added.
