e to isolate the
poison and prescribe medication. But"--he held up a four-cent
stamp--"here's the villain, gentlemen."

The big brass stood stunned and shocked. Mouths flapped open and eyes
bugged at Andy, at the stamp.

Bettijean said, "Sure. College kids and engaged girls and new parents
and especially writers and artists and poets--they'd all lick lots of
stamps. Professional men have secretaries. Big offices have
postage-meter machines. And government offices have free franking.
And"--she threw her arms around the sergeant's neck--"Andy, you're
wonderful."

"The old American ingenuity," the colonel said, reaching for Andy's
phone. "I knew we could lick it. Now all we have to do--"

"At ease, colonel," the brigadier said sharply. He waited until the
colonel had retreated, then addressed Andy. "It's your show. What do
you suggest?"

"Get somebody--maybe even the President--on all radio and TV networks.
Explain frankly about the four-centers and warn against licking any

accident--some chemical in the stickum spoiled. Do they keep the
stickum in barrels? Find out who had access. And ... oh, the phone
call. That was the lab. The antidote's simple and the cure should be
quick. They can phone or broadcast the medical information to doctors.
The man on the phone said they could start emptying hospitals in six
hours. And maybe we should release some propaganda. "United States
whips mystery virus," or something like that. And we could send the
Kremlin a stamp collection and.... Aw, you take it, sir. I'm pooped."

The general wheeled to fire a salvo of commands. Officers poured into
the corridor. Only the brigadier remained, a puzzled frown crinkling
his granite brow.

"But you said that postal workers weren't getting sick."

Andy chucked. "That's right. Did you ever see a post office clerk
lick a stamp? They always use a sponge."

The general looked to Bettijean, to Andy, to the stamp. He grinned and
the grin became a rumbling laugh. "How would you two like a thirty-day
