y at him, saw that his left hand reached
up for his ear, pulled down the lobe and released it with a jerk. A
little electric thrill went through Sahwah at the sight of that gesture.
There was only one person she had ever seen do that. That person was the
artist, Eugene Prince. In spite of the black matted hair that covered
the man's forehead, in spite of the black beard that covered the lower
half of his face, the tattered cap, the blue shirt and shabby working
clothes covered with red brick dust, something seemed to tell her that
this was the man the federal officers were now searching for high and
low.

"That's the spy!" she shouted at the top of her voice, to the utter
amazement of the others, but the driver started as if he had been shot.

Immediately Slim and the Captain jumped on him and he fought like a
tiger to get free. Others in the crowd came to the rescue and before
long Waldemar von Oldenbach was safely locked up, minus his black wig

undoing.

Sahwah was once more the heroine of the Winnebagos. "How did you ever
do it?" said Hinpoha enviously.

"Oh, I just noticed it," replied Sahwah without laying any claim
whatever to detective ability. Sahwah's ability to talk about her
achievements was as short as her power to think and act was long.

When Agent Sanders came to Oakwood to take the artist away with him he
asked to see the Winnebagos and complimented them all highly upon the
help they had given in catching the wily lieutenant, von Oldenbach. "I
wish to express the thanks of the government," he said formally, "in
consequence of the distinguished service rendered your coun
