“Yes, I suppose waiting another day will do no harm,” Arden agreed. “But I don’t believe Dimitri is in New York or has his box. He would not be where he is, a free agent, without sending some word to his brother Serge, at least, about himself. No, Dimitri is where he can’t get word to his friends.”

“And where do you think that place is?” asked Sim.

Arden shrugged her shoulders in a hopeless negative.

Time hanging heavy on their hands, the girls paid another visit to the houseboat but did not go on board. There was no sign of life about the Merry Jane save for Tania. She was shut up in what amounted to a kennel on the outside narrow deck, where the girls had put her on their last visit. There was plenty of food and water.

Poor Tania whined pitifully when she found that her friends were not coming to see her and departed without taking her with them.

“She misses Dimitri terribly,” said Arden.

“Yes,” agreed Sim.

The day passed and no word came from Serge. Later it developed that he was so frantically going from one to another of the friends of his brother in New York, a fruitless search, that he forgot all about his promise to communicate with the girls.

“Well, this settles it!” declared Arden as they were at breakfast the second day after the visit of Serge. The morning mail had come but brought no news. “I’m going to get the chief and visit Melissa and her father again.”

“Do you mean you’re going with him?” asked Terry.
