"I am afraid they would not be of the least assistance to us," he answered. "No, if we are to find him at all, we must do it on our own initiative. One thing is quite certain: he would not be likely to remain in the city any longer than he could help. There would always be the risk of your discovering his whereabouts. Now, the question we have to decide for ourselves is, where would he and where could he, go at such short notice? To decide that, we must find out whether he possessed sufficient money to take him very far. The manager of his bank and I are on excellent terms, and I feel sure, if we call upon him, he will give us all the information in his power."

"Let us call on him by all means," I answered; "and with as little delay as possible."

We accordingly set off once more, and, in due course, reached the bank. Passing to the private door, Brockford inquired whether the manager was at home, and, if so, whether he would see us. The servant replied that he had just returned, and we were forthwith conducted to his presence.

Having apologised for the intrusion, Brockford explained the reason of our visit. Max and the manager had always been great friends, and, in consequence, the latter was only too glad to do all that lay in his power to help us in our search. Begging us to be seated for a few moments, he retired into the business portion of the house, to presently return with the information that Max had not visited the bank that day.

"I happen to be aware that he had only a small sum in his pocket this morning," said Brockford. "I asked him for some change, and he could not give it to me. If he has not called here, or drawn a cheque on you and cashed it elsewhere, which he wouldn't be very likely to do, that settles the question of the money. Our next course is to find out what vessels have left the port, or are leaving, this afternoon."

After thanking the manager for his courtesy, we left the bank and once more returned to the harbour. After diligent inquiry there, we discovered that only two vessels had left the port that afternoon. One was bound to Bahia and the north; the other for Buenos Ayres and the south. The first was only a small trading boat; the other a tramp steamer of three thousand five hundred tons. The first, after inquiry, we dismissed from consideration. To the agents of the second we repaired in hot haste. It was just possible we had the key to the mystery in our hands.

"No," said the clerk, who waited upon us, in response to our inquiries, "I am quite sure no fresh hand was taken on board in Rio, and I am equally certain that she carried no passengers."

So minute and searching were our inquiries that it was well-nigh midnight before we had finished them. As on the previous occasions, Max had disappeared without, apparently, leaving a clue of any sort behind, to tell us of his whereabouts.

Next morning we were early at work again. By mid-day we had visited all the principal hotels, and many of less repute, had made inquiries at the various labour offices, at the railway stations, had interrogated the police and harbour officials, but still without success.

All that afternoon we continued our inquiries, on the day following also, and so on, day after day, for upwards of a month. In Mr. Brockford's company I scoured the country in railway trains, on horseback, and on foot. But always with the same result.
