In the light of the cabin the three detectives were revealed as startlingly alike. Barton Ward and Watson Bard, Barnstable's two assistants, might, indeed, almost have been taken for Barnstable himself, at a casual glance. In height, in bulk, in dress, in facial expression, they seemed Wilton Barnstable all over again. But, looking intently at the three men, Cleggett began to perceive a difference between the real Wilton Barnstable and his two counterfeits. It was the difference between the face which is informed of genius, and the countenance which is indicative of mere talent.
"Mr. Cleggett," began Wilton Barnstable, "as I said before, I will make no attempt to mystify you. I was a witness to the attack upon your vessel. Mr. Ward, Mr. Bard, and myself, in fact, had determined to assist you, had we seen that the combat was going against you. We lay, during the struggle, in the lee of your—your—er, schooner!—in the lee of your schooner, armed, and ready to bear a hand. We have our own little matter to settle with Logan Black. Why Logan Black should desire possession of this particular box, I am unable to state. Nevertheless, at the moment when he was leading his assault upon your starboard bow, two of his men, who had made a detour to the stern of your vessel, had clambered stealthily aboard, and were quietly pushing the box over the side into the canal. They let themselves down into the water, and swam towards the mouth of the canal, pushing it ahead of them. We followed in our rowboat, Mr. Ward, Mr. Bard, and myself, at a discreet distance. We let them push the box as far south as the Annabel Lee. And then——"
He paused a moment, and smiled reminiscently. Barton Ward and Watson Bard also smiled reminiscently, and the three detectives exchanged crafty glances.
"Then, to be brief, we took the box away from them. They were so ill-advised as to struggle. They are in irons, now, on board the Annabel Lee.
"But what I cannot understand, Mr. Cleggett, is why these men should risk so much to make off with an empty box."
"An empty box!" cried Cleggett.
"Empty!" echoed Lady Agatha and Miss Pringle, in concert.
The detective wrenched the cover from the box of Reginald Maltravers.
"Practically empty, at any rate," he said.
And, indeed, except for a few wads of wet excelsior, there was nothing in the box of Reginald Maltravers.
