"And you left her--"

"At a cheap hotel where I can find her again. And I guess it's up to
us to start right away."

"Yes," nodded Jack. "And we can't start too soon."

It may have occurred to Lieutenant Ridder that he wasn't exactly being
consulted. However, he saw that these submarine boys were used to
acting swiftly, and he began to believe that they would work better
if left to their own devices. So he merely nodded, adding:

"I'll wait here. I'll hope to have a report before long."

Eph led his two comrades back unerringly to the cheap hotel. They went
straight to the hotel desk, Jack asking, bluntly, whether any very
tall woman, in gray, and carrying a dress suit ease, had registered
there.

"No," replied the clerk, very positively.

Then they interviewed the porter. He remembered the "woman" having
stepped inside the hotel. She readjusted her veil in the lobby near
the doorway.

"Then she went outside, spoke to a driver, got into his cab, and went
away," continued the porter.

"She spoke to the driver, did she?" Eph asked.
