The glance he gave the house was but momentary, but in that glance the father saw all that he had secretly dreaded.  As his son’s eye fell on that fluttering bit of crape, testifying to another death in this already much-bereaved community, he staggered wildly, then in a pause of doubt drew nearer and nearer till his fingers grasped this symbol of mourning and clung there.  Next moment he was far down the road, plunging toward home in a state of great mental disorder.

A half-hour afterwards Mr. Sutherland reached home.  He had not overtaken Frederick again, or even his accompanying shadow.  Ascertaining at his own door that his son had not yet come in, but had been seen going farther up the hill, he turned back again into the road and proceeded after him on foot.

The next place to his own was occupied by Mr. Halliday.  As he approached it he caught sight of a man standing half in and half out of the honeysuckle porch, whom he at first thought to be Frederick.  But he soon saw that it was the fellow who had been following his son all the way from Portchester, and, controlling his first movement of dislike, he stepped up to him and quietly said: 

“Sweetwater, is this you?”

The young man fell back and showed a most extraordinary agitation, quickly suppressed, however.  “Yes, sir, it is no one else.  Do you know what I am doing here?”

“I fear I do.  You have been to Portchester.  You have seen my son—­ "

Sweetwater made a hurried, almost an entreating, gesture.

“Never mind that, Mr. Sutherland.  I had rather you wouldn’t say anything about that.  I am as much broken up by what I have seen as you are.  I never suspected him of having any direct connection with this murder; only the girl to whom he has so unfortunately attached himself.  But after what I have seen, what am I to think? what am I to do?  I honour you; I would not grieve you; but—­but—­ oh, sir, perhaps you can help me out of the maze into which I have stumbled.  Perhaps you can assure me that Mr. Frederick did not leave the ball at the time she did.  I missed him from among the dancers.  I did not see him between twelve and three, but perhaps you did; and—­and—­”

His voice broke.  He was almost as profoundly agitated as Mr. Sutherland.  As for the latter, who found himself unable to reassure the other on this very vital point, having no remembrance himself of having seen Frederick among his guests during those fatal hours, he stood speechless, lost in abysses, the depth and horror of which only a father can appreciate.  Sweetwater respected his anguish and for a moment was silent himself.  Then he burst out: 

“I had rather never lived to see this day than be the cause of shame or suffering to you.  Tell me what to do.  Shall I be deaf, dumb—­”

Here Mr. Sutherland found voice.

“You make too much of what you saw,” said he.  “My boy has faults and has lived anything but a satisfactory life, but he is not as bad as you would intimate.  He can never have taken life.  That would be incredible, monstrous, in one brought up as he has been.  Besides, if he were so far gone in evil as to be willing to attempt crime, he had no motive to do so; Sweetwater, he had no motive.  A few hundred dollars but these he could have got from me, and did, but—­”
