in without his knowing it."

"Oho! So your father has the other members of the family stationed
where they can see you, whichever way you go into the house?"
asked Reade, with genuine interest in the unfortunate Timmy.

"Nope," explained Timmy, with another shiver. "Mother and sister
are away visiting, and pop is all alone in the house."

"But he can't watch both the front and back doors at the same
time," Reade suggested hopefully.

"Can't he do just that, though?" sputtered Timmy. "I've been
scouting on tip-toe around the house to get the lay of the land.
Pop is smoking his pipe, and has placed his chair so that he
can see both the back and the front doors, for he has the room
doors open right through. There isn't a ghost of a show to get
in without being seen---and pop has the strap on a chair beside
him!" finished Timmy, with an anticipatory shiver.

"Timmy, you're a fearfully slow boy," Tom drawled.

"What do you mean?"

"I can fix it so you can get into the house while your father
is doing something else," Tom declared.

"Can you? How? Ring the front door bell, while I slip in at
the back door?"
