y, "that you've
shtumbled on the inside of a crime that doesn't show on the outside.
Many of the things you mention are so plain that he who runs may read;
but I've remarked that it's just the things ye don't suspect in real
life that prove to be the most important."

"That is true, Major," commented Louise. "At first it was just to amuse
ourselves that we became amateur detectives, but the developments are so
startling and serious that we now consider it our duty to uncover the
whole dreadful crime, in the interests of justice."

"Just so," he said, nodding.

"But I'm sure Old Hucks is innocent!" declared Patsy, emphatically.

"Then he is," asserted the Major; "for Patsy's always right, even when
she's wrong. I've had me eye on that man Hucks already, for he's the
merriest faced villain I ever encountered. Do you say he's shy with
you girls?"

"He seems afraid of us, or suspicious, and won't let us talk to him,"

Thomas Hucks, or the timber-toed book agent, or the respectable hardware
man. Being invited to come and do his worst, he passed himself as a
docther on a fishing excursion, and having with deliberate intent
murthered Captain Wegg, got himself called by the coroner to testify
that the victim died of heart disease. A very pretty bit of
scoundrelism; eh, me dears?"

"But the robber--who do you think he was?" asked Louise.

"That I've still to discover. You inform me that Hucks is eager for
money and acts like a miser. I've seen the time I was eager for money
meself, and there's not a miserly hair on me bald head. But exceptions
prove the rule. I'll watch our smiling Thomas and make a report later."

Within half an hour he was telling Hucks a funny story and slapping the
old man upon the back as familiarly
