Terry and Sim agreed silently as Olga appeared at the steps. Tania barked furiously at the sight of her and strained to get loose. Olga, casting the merest glance in the direction of the animal, at once went inside the houseboat. The three girls followed close behind her. She did not hesitate in the living room. But, walking briskly, pushed aside the curtains and stopped short as the broken cupboard caught her eye. The mysterious covered canvas might not have been there for all the notice she gave it.

“Who did that?” she asked, angrily turning to the girls. “Who? Tell me at once!”

“We found it that way,” Arden answered. “What’s the matter?”

“Matter?” Olga repeated. “Did you not know, then, that Dimitri had here a gold box worth a fortune? Come! I see by your faces you did know. This is where he kept it. I told him it was foolish. After all, one can get around Tania with a piece of raw beef. Yes!”

She was quite beside herself with rage. Her dark eyes flashed, and she bit her lips impatiently. Then, apparently realizing how odd all this must seem to the girls and shrugging her shoulders, she attempted to make light of the incident. With another shrug of her expressive shoulders, she said:

“But of course he has removed his precious box with him. He can take care of himself, that one. Ha! Yes! There is no use wasting time here. I must get back to New York—quickly!”

Olga fumbled in her bag and pulled out a gaudy compact. At the same time a paper fell but, though she did not notice it, none of the girls attempted to pick it up. The whole affair seemed to rob them of their natural intelligence. Olga’s personality was so overpowering.

“But,” Arden began, “why should he break open the cupboard? Surely he had a key.”

“I have known him to lose things more important than keys. Don’t worry your pretty heads over it, Dimitri is not harmed, I am sure of it.” Olga used her compact vigorously. All that she did was vigorous.

“And Tania,” Sim reminded her. “He left nothing for her to eat.”
