"Impossible to say," was the smiling answer. "The caller forgot to leave a card. But someone has cleaned us out of about a dozen tins of food and some packages of biscuit. It must have been quite a little load. Just by chance I also happened to think to look at my medicine case. One vial is missing therefrom."
"What medicine did he take, did you say, sir?" asked Dave Darrin much interested.
"I believe I didn't say," replied Dr. Bentley. "Perhaps later on I shall tell you."
"If the thief took only a dozen tins," said Mrs. Bentley, "there is food enough left so that we needn't worry about immediate famine. And we have two cars, either one of which may be despatched to bring further supplies."
"Tag is really going to move away from here, then," decided Dick thoughtfully.
"Why do you say that?" asked Dr. Bentley.
"Because Tag has a fine appetite, and an abundance of muscle. Instead of a dozen tins he would have taken three or four times that amount. It is only his need for traveling in light marching order that made him so moderate in the tax he levied."
"It's only an incident," continued Dr. Bentley. "And I am glad of it. It shows that the young scamp is still in this neighborhood, and that means that there is still a fair chance of his being captured."
"I wonder why he stole one particular drug from your case?" Dick mused aloud.
Dr. Bentley smiled, not relieving Prescott's curiosity as to the name of the missing drug.
