living-room and again considered her defenses.

Three points of access from the terrace to the house--the door that
led into the alcove, the French windows of the living room--the
billiard-room window. On the other side of the house there was the
main entrance, the porch, the library and dining-room windows. The
main entrance led into a hall-living-room, and the main door of the
living-room was on the right as one entered, the dining-room and
library on the left, main staircase in front. "My mind is starting
to go round like a pinwheel, thinking of all those windows and doors,"
she murmured to herself. She sat down once more, and taking a pencil
and a piece of paper drew a plan of the lower floor of the house.

And now I've studied it, she thought after a while, I'm no further
than if I hadn't. As far as I can figure out, there are so many
ways for a clever man to get into this house that I'd have to be a
couple of Siamese twins to watch it properly. The next house I rent
in the country, she decided, just isn't going to have any windows
and doors--or I'll know the reason why.

But of course she was not entirely shut off from the world, even
if the worst developed. She considered the telephone instruments
on a table near the wall, one the general phone, the other
connecting a house line which also connected with the garage and
the greenhouses. The garage would not be helpful, since Slocum,
her chauffeur for many years, had gone back to England for a visit.
Dale had been driving the car. But with an able-bodied man in the
gardener's house--

She pulled herself together with a jerk.
