They went to a small room marked INTERIM CONFINEMENT。 It contained a half…dozen couches with plastic disposable covers over them。
Stone said； 〃Better relax。 Sleep if you can。 We'll need all the rest we can get before Level V。 〃 He walked over to Hall。 〃How did you find the decontamination procedure？〃
〃Interesting；〃 Hall said。 〃You could sell it to the Swedes and make a fortune。 But somehow I expected something more rigorous。〃
〃Just wait；〃 Stone said。 〃It gets tougher as you go。 Physicals on Levels III and IV。 Afterward there will be a brief conference。〃
Then Stone lay down on one of the couches and fell instantly asleep。 It was a trick he had learned years before； when he had been conducting experiments around the clock。 He learned to squeeze in an hour here； two hours there。 He found it useful。
***
The second decontamination procedure was similar to the first。 Hall's yellow clothing； though he had worn it just an hour； was incinerated。
〃Isn't that rather wasteful？〃 he asked Burton。
Burton shrugged。 〃It's paper。〃
〃Paper？ That cloth？〃
Burton shook his head。 〃Not cloth。 Paper。 New process。〃
They stepped into the first total…immersion pool。 Instructions on the wall told Hall to keep his eyes open under water。 Total immersion； he soon discovered； was guaranteed by the simple device of making the connection between the first room and the second an underwater passage。 Swimming through； he felt a slight burning of his eyes； but nothing bad。
The second room contained a row of six boxes； glass…walled； looking rather like telephone booths。 Hall approached one and saw a sign that said； 〃Enter and close both eyes。 Hold arms slightly away from body and stand with feet one foot apart。 Do not open eyes until buzzer sounds。 BLINDNESS MAY RESULT FROM EXPOSURE TO LONG…WAVE RADIATION。〃
He followed the directions and felt a kind of cold heat on his body。 It lasted perhaps five minutes； and then he heard the buzzer and opened his eyes。 His body was dry。 He followed the others to a corridor； consisting of four showers。 Walking down the corridor； he passed beneath each shower in turn。 At the end； he found blowers； which dried him； and then clothing。 This time the clothing was white。
They dressed； and took the elevator down to Level III。
***
There were four nurses waiting for them； one took Hall to an examining room。 It turned out to be a two…hour physical examination； given not by a machine but by a blank…faced； thorough young man。 Hall was annoyed； and thought to himself that he preferred the machine。
The doctor did everything； including a plete history birth； education； travel； family history； past hospitalizations and illnesses。 And an equally plete physical。 Hall became angry； it was all so damned unnecessary。 But the doctor shrugged and kept saying； 〃It's routine。〃
After two hours； he rejoined the others； and proceeded to Level IV。
***
Four total…immersion baths； three sequences of ultraviolet and infrared light； two of ultrasonic vibrations； and then something quite astonishing at the end。 A steel…walled cubicle； with a helmet on a peg。 The sign said； 〃This is an ultraflash apparatus。 To protect head and facial hair； place metal helmet securely on head； then press button below。〃
Hall had never heard of ultraflash； and he followed directions； not knowing what to expect。 He placed the helmet over his head； then pressed the button。
There was a single； brief； dazzling burst of white light； followed by a wave of heat that filled the cubicle。 He felt a moment of pain； so swift he hardly recognized it until it was over。 Cautiously； he removed the helmet and looked at his body。 His skin was covered with a fine； white ash and then he realized that the ash was his skin； or had been： the machine had burned away the outer epithelial layers。 He proceeded to a shower and washed the ash off。 When he finally reached the dressing room； he found green uniforms。
***
Another physical。 This time they wanted samples of everything： sputum； oral epithelium； blood； urine； stool。 He submitted passively to the tests； examinations； questions。 He was tired； and was beginning to feel disoriented。 The repetitions； the new experiences； the colors on the walls； the same bland artificial light。。。
Finally； he was brought back to Stone and the others。 Stone said； 〃We have six hours on this level that's protocol； waiting while they do the lab tests on us so we might as well sleep。 Down the corridor are rooms； marked with your names。 Further down is the cafeteria。 We'll meet there in five hours for a conference。 Right？〃
Hall found his room； marked with a plastic door tag。 He entered； surprised to find it quite large。 He had been expecting something the size of a Pullman cubicle； but this was bigger and better…furnished。 There was a bed； a chair； a small desk； and a puter console with built…in TV set。 He was curious about the puter； but also very tired。 He lay down on the bed and fell asleep quickly。
***
Burton could not sleep。 He lay in his bed on Level IV and stared at the ceiling； thinking。 He could not get the image of that town out of his mind； or those bodies； lying in the street without bleeding。。。
Burton was not a hematologist； but his work had involved some blood studies。 He knew that a variety of bacteria had effects on blood。 His own research with staphylococcus； for example； had shown that this organism produced two enzymes that altered blood。
One was the so…called exotoxin； which destroyed skin and dissolved red cells。 Another was a coagulase； which coated the bacteria with protein to inhibit destruction by white cells。
So it was possible that bacteria could alter blood。 And it could do it many different ways： strep produced an enzyme； streptokinase； that dissolved coagulated plasma。 Clostridia and pneumococci produced a variety of hemolysins that destroyed red cells。 Malaria and amebae also destroyed red cells； by digesting them as food。 Other parasites did the same thing。
So it was possible。
But it didn't help them in finding out how the Scoop organism worked。
Burton tried to recall the sequence for blood clotting。 He remembered that it operated like a kind of waterfall： one enzyme was set off； and activated； which acted on a second enzyme； which acted on a third； the third on a fourth； and so on； down through twelve or thirteen steps； until finally blood clotted。
And vaguely he remembered the rest； the details： all the intermediate steps； the necessary enzymes； the metals； ions； local factors。 It was horribly plex。
He shook his head and tried to sleep。

Leavitt； the clinical microbiologist； was thinking through the steps in isolation and identification of the causative organism。 He had been over it before； he was one of die original founders of the group； one of the men who developed the Life Analysis Protocol。 But now； on the verge of putting that plan into effect； he had doubts。
Two years before； sitting around after lunch； talking speculatively； it had all seemed wonderful。 It had been an amusing intellectual game then； a kind of abstract test of wits。 But now； faced with a real agent that caused real and bizarre death； he wondered whether all their plans would prove to be so effective and so plete as they once thought。
The first steps were simple enough。 They would examine the capsule minutely and culture everything onto growth media。 They would be hoping like hell to e up with an organism that they could work with； experiment on； and identify。
And after that； attempt to find out how it attacked。 There was already the suggestion that it killed by clotting the blood； if that turned out to be the case； they had a good start； but if not； they might waste valuable time following it up。
The example of cholera came to mind。 For centuries； men had known that cholera was a fatal disease； and that it caused severe diarrhea； sometimes producing as much as thirty quarts of fluid a day。 Men knew this； but they someh
