“Yes, sir—­about eight.”

“Could you say exactly eight?”

“Well, no, I couldn’t be that exact.”

“Um.  If a person had been passing along there just about that time, he would have been almost sure to encounter that assassin, do you think?”

“Yes, I should think so.”

“Thank you, that is all.  For the present.  I say, all for the present.”

“Dern him, he’s laying for Archy,” said Ferguson.

“It’s so,” said Ham Sandwich.  “I don’t like the look of it.”

Stillman said, glancing at the guest, “I was along there myself at half-past eight—­no, about nine.”

“In-deed?  This is interesting—­this is very interesting.  Perhaps you encountered the assassin?”

“No, I encountered no one.”

“Ah.  Then—­if you will excuse the remark—­I do not quite see the relevancy of the information.”

“It has none.  At present.  I say it has none—­at present.”

He paused.  Presently he resumed:  “I did not encounter the assassin, but I am on his track, I am sure, for I believe he is in this room.  I will ask you all to pass one by one in front of me—­here, where there is a good light—­so that I can see your feet.”

A buzz of excitement swept the place, and the march began, the guest looking on with an iron attempt at gravity which was not an unqualified success.  Stillman stooped, shaded his eyes with his hand, and gazed down intently at each pair of feet as it passed.  Fifty men tramped monotonously by—­with no result.  Sixty.  Seventy.  The thing was beginning to look absurd.  The guest remarked, with suave irony: 

“Assassins appear to be scarce this evening.”

The house saw the humor if it, and refreshed itself with a cordial laugh.  Ten or twelve more candidates tramped by—­no, danced by, with airy and ridiculous capers which convulsed the spectators—­then suddenly Stillman put out his hand and said: 

“This is the assassin!”

“Fetlock Jones, by the great Sanhedrim!” roared the crowd; and at once let fly a pyrotechnic explosion and dazzle and confusion of stirring remarks inspired by the situation.

At the height of the turmoil the guest stretched out his hand, commanding peace.  The authority of a great name and a great personality laid its mysterious compulsion upon the house, and it obeyed.  Out of the panting calm which succeeded, the guest spoke, saying, with dignity and feeling: 

“This is serious.  It strikes at an innocent life.  Innocent beyond suspicion!  Innocent beyond peradventure!  Hear me prove it; observe how simple a fact can brush out of existence this witless lie.  Listen.  My friends, that lad was never out of my sight yesterday evening at any time!”

It made a deep impression.  Men turned their eyes upon Stillman with grave inquiry in them.  His face brightened, and he said: 

“I knew there was another one!” He stepped briskly to the table and glanced at the guest’s feet, then up at his face, and said:  “You were with him!  You were not fifty steps from him when he lit the candle that by and by fired the powder!” (Sensation.) “And what is more, you furnished the matches yourself!”
