Grey feeling entirely safe walked away in the heavy rain with a mind at ease and a little sorry as a soldier for the hapless situation with which Penhallow had had to struggle. When we have known men only in the every-day business of life or in ordinary social relations, we may quite fail to credit them with qualities which are never called into activity except by unusual circ.u.mstances. Grey, an able engineer, regarded Penhallow as a rather slow thinker, a good man of business, and now as a commonplace, well-mannered officer. He smiled as he thought how his sister had made her husband in this present predicament what algebraists call a "negligible quant.i.ty." He would have been less easy had he known that the man he left felt keenly a sense of imperilled honour and of insult which his relation to Grey forbade him to avenge. He had become a man alert, observant, and quick to see his way and to act.

Josiah, with all his hunting instincts aroused, loitered idly after Grey in the rain, one of the scores of lazy, unnoticeable negroes. He was gone all the afternoon, and at eight o'clock found Penhallow in his room. "Did you find where he lives?" asked the Colonel.

"That man, he lives at 229 Sixteenth Street. Two more live there. They was in and out all day-and he went to shops and carried things away-"

"What kind of shops?"

"Where they sell paper and pens-and 'pothecaries."

"Sit down-you look tired." It was plain that they were soon about to move and were buying what was needed in the South-quinine, of course. But what had been their errand? He said, "Get some supper and come back soon."

Then he sat down to think. An engineer of competence lately back from Europe! His errand-their errand-must be of moment. He took a small revolver out of a drawer, put in sh.e.l.ls, placed it in his breast pocket, and secured a box of matches. About nine, in a summer thunder-shower of wind and rain, he followed Josiah and walked to No. 229 Sixteenth Street. As he stood he asked,

"How did those men get in, Josiah?"

"All had keys. Want to get in, Colonel?"

"Yes, I want to get in. Are there any others in the house-servants-any one?"

"No, sir," Josiah said. "I went round to an alley at the back of the house. There are lights on the second storey. You can get in easy at the back, sir."

Seeing a policeman on the opposite pavement, Penhallow at once changed his plan of entrance, and crossing the street said to the policeman, "Is this your beat?"

"Yes, sir."

"Very good! You see I am in uniform. Here is my card. I am on duty at the War Department. Here is my general pa.s.s from the Provost-marshal General. Come to the gas lamp and read it. Here are ten dollars. I have to get into No. 229 on Government business. If I do not come out in thirty minutes, give the alarm, call others and go in. Who lives there?"

"It is a gambling house-or was-not now."

"Very good. This is my servant, Josiah. If I get out safely, come to Willard's to-morrow at nine-use my card-ask for me-and you will not be sorry to have helped me."

"You want to get in!"

"Yes."

"No use to ring, sir," said Josiah. "There ain't any servants and the gentlemen, they ate outside. Lord, how it rains!"

The policeman hesitated. Another ten dollar note changed owners. "Well, it isn't police duty-and you're not a burglar-"

The Colonel laughed. "If I were, I'd have been in that house without your aid."

"Well, yes, sir. Burglars don't usually take the police into their confidence. There are no lights except in the second storey. If your man's not afraid and it's an honest Government job, let him go through that side alley, get over the fence-I'll help him-and either through a window or by the cellar he can get in and open the front door for you."

Josiah laughed low laughter as he crossed the street with the officer and was lost to view. The Colonel waited at the door. In a few minutes the man returning said, "Want me with you? He got in easily."

"No, but take the time when I enter and keep near." They waited.

"Nine-thirty now, sir."

"Give me the full time."

Penhallow went up the steps and knocked at the door. It was opened and he went in. "Shut the door quietly, Josiah-open if the policeman knocks. Now, be quiet, and if you hear a shot, or a big row call the police."

The house below-stairs was in darkness. He took off his shoes and went into a room on the first floor. Striking a match, he saw only ordinary furniture. The room back of it revealed to his failing match a roulette table. He went out into the hall and up the stairs with the utmost caution to avoid noise. On the second floor the door of the front room was ajar. They must be careless and confident, he reflected as he entered. A lighted candle on a pine table dimly illuminated a room in some confusion. On the floor were two small bags half full of clothes which he swiftly searched, without revealing anything of moment. A third, smaller bag lay open on the table. It contained a number of small rolls of very thin paper, and on the table there were spread out two others. As he looked, he knew they were admirably drawn sketches of the forts and the lines of connecting works which defended the city. Making sure no more papers were to be found, he thrust all of them within his waistcoat, b.u.t.toned it securely, felt for his revolver, and listened.

In the closed back room there was much mirth and the clink of gla.s.ses. He drew near the door and felt certain that Grey was relating with comic additions his interview of the morning. Without hesitation he threw open the door as three men sprang to their feet and Grey covered him with a revolver. He said quietly, "Sorry to disturb you, gentlemen. Put down that toy, Grey."

"No, by Heaven!-not till-"

"My dear Grey, between me and that pistol stands a woman-as she stood for your safety this morning. Men who talk, don't shoot. You are all three in deadly peril-you had better hear me. I could have covered you all with my revolver. Put down that thing!"

"Put it down," said the older of the three. Grey laid the weapon on the table.

"This is not war," said Penhallow, "and you are three to one. Sit down." He set the example. "It is clear that you are all Confederate officers and spies. Let us talk a little. I came on Mr. Grey to-day by accident. It was my duty to have him arrested; but he is my wife's brother. If a pistol is heard or I am not out of this, safe, in a few minutes, the police now on guard will enter-and you are doomed men. I am presumably on Government business. Now, gentlemen, will you leave at once or in an hour or less?"

"I for one accept," said the man who had been silent.

"And I," said the elder of the party.

"On your honour?"

"Yes."

Grey laughed lightly, "Oh, of course. Our work is done. Speed the parting guest!"

"I wish," said the Colonel, rising, "to leave no misapprehension on your minds-or on that of Mr. Grey. Those admirable sketches left carelessly on the table are in my pocket. Were they not, you would all three be lost men. Did you think, Grey, that to save your life or my own I would permit you to escape with your work? Had I not these papers, your chance of death would not weigh with me a moment."

Grey started up. "Don't be foolish, Grey," said the older man. "We have played and lost. There has been much carelessness-and we have suffered for it. I accept defeat, Colonel."

Penhallow looked at the watch in his hand. "You have ten minutes grace-no, rather less. May I ask of you one thing? You are every hour in danger, but I too am aware that if this interview be talked about in Richmond or you are caught, my name may be so used as to make trouble for me, for how could I explain that to save my wife's brother I connived at the escape of Confederate officers acting as spies? I ask no pledge, gentlemen. I merely leave my honour as a soldier in your hands. Good-night, and don't delay."

Grey was silent. The older man said, "I permit myself to hope we may meet some time under more pleasant circ.u.mstances-for me, I mean,"-he added, laughing. "Good-night."

Penhallow withdrew quickly and found Josiah on guard. He said, "It is all right-but for sport it beats possum-hunting. Open the door." The rain was still falling in torrents. "All right," he said to the policeman, "come and see me to-morrow early."

"What was the matter, sir? I've got to make my report."

Then Penhallow saw the possibility of trouble and as quickly that to bribe further might only make mischief. "Do not come to the hotel, but at eleven sharp call on me at the War Department on Seventeenth Street. You have my card. By that time I shall have talked the matter over with the Secretary. I am not at liberty to talk of it now-and you had better not. It is a Government affair. You go off duty, when?"

"At six. You said eleven, sir?"

"Yes, good-night. Go home, Josiah."

The Colonel was so wet that the added contributions of water were of no moment. The soldier in uniform may not carry an umbrella-for reasons unknown to me.

Before breakfast next morning Josiah brought him a letter, left at the hotel too late in the night for delivery. He read it with some amus.e.m.e.nt and with an uncertain amount of satisfaction:

"MY DEAR J: When by evil luck I encountered you, I was sure of three things. First, that I was safe; then, that we had secured what we wanted; and last, that our way home was a.s.sured. If in my satisfaction I played the bluff game rather lightly-well, in a way to annoy you-I beg now to apologize. That I should so stupidly have given away a game already won is sufficiently humiliating, and the dog on top may readily forgive. You spoilt a gallant venture, but, by Jove, you did it well! I can't imagine how you found me! Accept my congratulations.
