corner, retracing his steps in time to enter the store half a minute
before the errand boy got there.

The grocer was behind the counter. "Have you any crackers?" asked Roy.

The grocer took down a package of Uneeda biscuits.

"You don't have any loose ones?" asked Roy.

"No, these are all we keep."

"Guess I'll have to take 'em," said Roy. "Got any candy?"

"In the case there," was the answer.

Roy walked over to the show-case and began to examine the stock. Just
then the errand boy came in.

"Here's the money for the sugar," he said, handing the grocer a silver
dollar.

The grocer took the coin and carelessly dropped it into his pocket.

Roy continued his inspection of the stock of sweetmeats. "Give me five
cents' worth of gum-drops," he said.

The grocer began to weigh them out. A tall man with gauntlets and with
motor goggles on his forehead came in.

"Hello, Fritz," he said jovially. "Got that sugar for me yet?"

"Just sold my last ounce," said the grocer. "I haven't been able to
get a bit for three days."

"Himmel!" said the customer. "How much longer have I got to go without

He turned to go.

"Hello!" called the grocer. "Here's that dollar I owe you."

The man turned back, and the grocer pulled the coin from his pocket and

grocer a dollar that he had collected for sugar. Pretty soon an
automobile driver came in to get some sugar and the grocer said he
hadn't any more, but he paid him a dollar he owed him."

Willie was silent, turning the matter over in his mind. "Then what?"
he asked after a time.

"Nothing, except that I bought some candy and the grocer put the money
in his cash drawer. Then I left."

"Where else would he put it?" asked Willie, abstractedly, as he tried
to read some meaning into the grocer's apparently meaningless acts.

"Well," said Roy, "he didn't put the dollar the errand boy gave him
into the drawer. He dropped that into his pocket."

"Why, that's exactly what happened when I was in there the other day,"
said Willie in surprise.

The daylight waned. Dusk came on. It grew too dark to see the spy's
