Without pause, and three steps at a time, Darrow ran down three flights of stairs. Then, recovering from his initial excitement somewhat, he caught the elevator and shot to the street. There he walked rapidly to the subway, which he took as far as City Hall Square. On emerging from the subway station he started across for the _Despatch_ office as fast as he could walk. By the entrance to the City Hall, however, he came to an abrupt halt. From the open doorway rushed his friend, Officer Burns, of the City Hall Station. The policeman's face was chalky white; his eyes were staring, his cap was over one side, he staggered uncertainly. As he caught sight of Darrow he stumbled to the young man and clung to his neck, muttering incoherently. People passing in and out looked at him curiously and smiled.

"My God!" gasped Burns, his eyes roving. "I says to him, 'Mike, I don't wonder you've got cold feet.' And there he was, and the mayor--Heaven save--and his secretary! My God!"

Darrow shook his shoulder.

"Here," he said decisively, "what are you talking about? Get yourself together! Remember you're an officer; don't lose your nerve this way!"

At the touch to his pride Burns did pull himself together somewhat, but went on under evident strong excitement.

"I went in just now to the mayor's office a minute," said he, "and saw my friend Mike Mallory, the doorkeeper, settin' in his chair, as usual. It was cold-like, and I went up to him and says, 'Mike, no wonder you get cold feet down here,' just by way of a joke; and when he didn't answer, I went up to him, and he was dead, there in his chair!"

"Well, you've seen dead men before. There's no occasion to lose your nerve, even if you did know him," said Darrow.

The brutality of the speech had its intended effect. Burns straightened.

"That's all very well," said he more collectively. "_But the man was froze_!"

"Frozen!" muttered Darrow, and whistled.

"Yes, and what's more, his little dog, setting by the chair, was froze, too; so when I stepped back sudden and hit against him, he tumbled over _bang_, like a cast-iron dog! That got my goat! I ran!"

"Come with me," ordered Darrow decisively.

They entered the building and ran up the single flight of stairs to the second-story room which the mayor of that term had fitted up as a sort of private office of his own. A sharp chill hung in the hallways; this increased as they neared the executive's office. Outside the door sat the doorkeeper in his armchair. Beside him was a dog, in the attitude of an animal seated on its haunches, but lying on its side, one fore leg sticking straight out. Darrow touched the man and stooped over to peer in his face. The attitude was most lifelike; the color was good. A deadly chill ran from Darrow's finger tips up his arm.

He pushed open the door cautiously and looked in.

"All right, Burns," said he. "The atmosphere has become gaseous again. We can go in." With which strange remark he entered the room, followed closely, but uncertainly by the officer.

The private office possessed the atmosphere of a cold-storage vault. Four men occupied it. At the desk was seated the mayor, leaning forward in an attitude of attention, his triple chin on one clenched fist, his heavy face scowling in concentration. Opposite him lounged two men, one leaning against the table, the other against the wall. One had his hand raised in argument, and his mouth open. The other was watching, an expression of alertness on his sharp countenance. At a typewriter lolled the clerk, his hand fumbling among some papers.

The group was exceedingly lifelike, more so, Darrow thought, than any wax figures the Eden Musee had ever placed for the mystification of its country visitors. Indeed, the only indication that the men had not merely suspended action on the entrance of the visitors was a fine white rime frost that sparkled across the burly countenance of the mayor. Darrow remembered that, summer and winter, that dignitary had always perspired!

Burns stood by the door, rooted to the spot, his jaw dropped, his eye staring. Darrow quite calmly walked to the desk. He picked up the inkstand and gazed curiously at its solidified contents, touched the nearest man, gazed curiously at the papers on the desk, and addressed Burns.

"These seem to be frozen, too," he remarked almost sleepily, "and about time, too. This is a sweet gang to be getting together on this sort of a job!"

Quite calmly he gathered the papers on the desk and stuffed them into his pocket. He picked up the desk telephone, giving a number. "Ouch, this receiver's cold," he remarked to Burns. "Hello, _Despatch_. Is Hallowell in the office? Just in? Send him over right quick, keen jump, City Hall, mayor's second-story office. No, right now. Tell him it's Darrow."

He hung up the receiver.

"Curious phenomenon," he remarked to Burns, who still stood rooted to the spot. "You see, their bodies were naturally almost in equilibrium, and, as they were frozen immediately, that equilibrium was maint............
