reminded his friend.

"I know that and I think it's a good plan. All I say is that she may fool
us in some way if we're not careful."

"How do you suppose Mr. Wernberg's getting along in the hospital?"

"I don't know," said Hugh. "I must say though that I'm more
interested in Lena."

"I'd like to see our old friend, the false detective."

"So would I. What do you suppose he is--"

"Ssh," hissed Bob suddenly.

Around the corner of the Cooks' house came a woman. She walked briskly
and a moment later had reached the street. She gazed apprehensively up
and down while the two boys shrank farther back into the shadow; then she
started off in the direction of the city's business district.

"That's Lena," whispered Bob. "Come on."

On the opposite side of the street and perhaps a hundred paces in back of
the hurrying woman the two boys followed.

"We'll have to keep closer than this when she gets down town,"
whispered Hugh.

"I know it," agreed Bob. "She'd get suspicious now though."
