"I didn't think of it," she wailed. "Nick said he'd have to make some preparations, and I never dreamed he'd skip away like this."

"He must have gone home directly after you left him, and skipped out immediately," said the Doctor ruminatively. "Mueller never caught up with him."

"But what'll we do?" she cried desperately.

"He can't have gone far with no more preparation than this," soothed Horker. "He'll write you in a day or two."

"He won't! He said he wouldn't. He doesn't want me to know where he is!" She was on the verge of tears.

"Now, now," said the Doctor still in his soothing tones. "It isn't as bad as all that."

"Take off your bed-side manner!" she snapped, blinking to keep back the tears. "It's worse! What ever can we do? Dr. Carl," she changed to a pleading tone, "can't you think of something?"

"Of course, Pat! I can think of several things to do if you'll quiet down for a moment or so."

"I'm sorry, Dr. Carl—but what can we do?"

"First, perhaps Mueller can trace him. That's his business, you know."
