One look was enough. The kindly expression faded from his handsome features. His face turned to flame. The veins of his forehead swelled with passion, and he strode forward as though he would lay hands on the intruder. "How dare you," he cried when he could find his voice--"how dare you follow me? How dare you play the spy upon me, sir? Speak!"
But Jack--for Jack it was--had no answer ready. He seemed to have lost for once (astonished at being taken in this way, perhaps) his presence of mind. "I do not--understand," he said helplessly.
"Understand? You understand," the Archdeacon cried, his son's very confusion condemning him unheard, "that you have meanly followed me to--to detect me in--in----" And then he came to a deadlock, and, redder than before, thundered, "Are you not ashamed of yourself, sir?"
"I thought I saw a back I knew," Jack muttered, looking everywhere but at his father, which was terribly irritating. "I was coming through the street."
"You were coming through the street? I suppose you often pass through Sidmouth Street!" retorted the Archdeacon with withering sarcasm. But his wrath was growing cool.
"Very often," said Jack so sturdily that his father could not but believe him, and was further sobered. "I saw a back I thought I knew, and I came in here. I had no intention of offending you, sir. And now I think I will go," he added, looking about him uneasily, "and--and speak to you another time."
But the Archdeacon's anger was quite gone now. A wretched embarrassment was taking its place as it dawned upon him that after all Jack might by pure chance have seen him enter and have followed innocently. In that case how had he committed himself by his outbreak--how indeed! "Jack," he said, "I beg your pardon. I beg your pardon, Jack. I see I was mistaken. Do not go, my boy, until I have explained to you why I am here. It is not," he went on, smiling a wretched smile at the pretty faces round him, "quite the place in which you would expect to find me."
"It is certainly not the place in which I did expect to find you," Jack said bluntly. And he looked about him, also in a dazed fashion, as if the Archdeacon and the photographs were not a conjunction for which he was prepared.
"No, no," assented the Archdeacon, wincing, however. "But it is the simplest piece of business in the world which has brought me here." And he recalled to his son's memory their talk at the club.
"Ah, I understand!" Jack said, as if he did, too. "You have come about your friend's business."
