A Sidewalk Going Nowhere, conclusion

(This story will make more sense, if you start here.)

It has been quiet for several days now.
A preliminary investigation of the premises has revealed the following:

Last weekend a small attic space was emptied of doll beds, spirograph wheels, beanbag chairs and all those must-have items that reside there for whatever small children at some time may come into our lives--and a panel removed connecting house to porch ceiling. From here, perhaps to get a glimpse of the stealthy creature or a tell-tale remnant of his passing.
Armed with flashlights and stooping low in the dark, unfinished space, we poked out our heads--prepared to meet anything from rats to raccoons, (or woodchucks, flying squirrels, gray squirrels, skunks, deer mice, bats,...) and found... nothing.

Carefully crawling from one joist to the next, every crack of daylight was evident, but none large enough to admit more than a wasp. The space behind the tall, 2-story wall, firmly sealed--no signs of forced entry. The intruder must have been let in through another point.

He'd covered his tracks well, and, although creating quite a commotion behind the tall wall, seemed to have left the immediate area undisturbed--taking nothing.

An outdoor inspection revealed a small gap in the soffit vent behind a gutter to be his point of entry. A canvass of the area turned up no eye-witnesses.

We secured the area, and continued surveillance for several days.
There has been no further indication of his presence.

Fred will continue to monitor the situation for evidence of undercover activity.
