The Spider.

“Thus far we run before the wind.”

IN the interview which Mr. Byrd had held with Miss Dare he had been conscious of omitting one test which many another man in his place would have made. This was the utterance of the name of him whom he really believed to be the murderer of Mrs. Clemmens. Had he spoken this name, had he allowed himself to breathe the words “Craik Mansell” into the ears of this agitated woman, or even gone so far as to allude in the most careless way to the widow’s nephew, he felt sure his daring would have been rewarded by some expression on her part that would have given him a substantial basis for his theories to rest upon.

But he had too much natural chivalry for this. His feelings as a man got in the way of his instinct as a detective. Nevertheless, he felt positive that his suspicions in regard to this nephew of Mrs. Clemmens were correct, and set about the task of fitting facts to his theory, with all that settled and dogged determination which follows the pursuit of a stern duty unwillingly embraced.

Two points required instant settling.

First, the truth or falsehood of his supposition as to the identification of the person confronted by Miss Dare in the Syracuse depot with the young man described by Miss Firman as the nephew of Widow Clemmens.

Secondly, the existence or non-existence of proof going to show the presence of this person at or near the house of Mrs. Clemmens, during the time of the assault.

But before proceeding to satisfy himself in regard to these essentials, he went again to the widow’s house and there spent an hour in a careful study of its inner and outer arrangements, with a view to the formation of a complete theory as to the manner and method of the murder. He found that in default of believing Mr. Hildreth the assailant, one supposition was positively necessary, and this was that the murderer was in the house when this gentleman came to it. A glance at the diagram on next page will explain why.

The house, as you will see, has but three entrances: the front door, at which Mr. Hildreth unconsciously stood guard; the kitchen door, also unconsciously guarded during the critical moment by the coming and going of the tramp through the yard; and the dining-room door, which, though to all appearance free from the surveillance of any eye, was so situated in reference to the clock at which the widow stood when attacked, that it was manifestly impossible for any one to enter it and cross the room to the hearth without attracting the attention of her eye if not of her ear.

To be sure, there was the bare possibility of his having come in by the kitchen-door, after the departure of the tramp, but such a contingency was scarcely worth considering. The almost certain conclusion was that he had been in the house for some time, and was either in the dining-room when Mrs. Clemmens returned to it from her interview with Mr. Hildreth, or else came down to it from the floor above by means of the staircase that so strangely descended into that very room.

Another point looked equally clear. The escape of the murderer — still in default of considering Mr. Hildreth as such — must have been by means of one of the back doors, and must have been in the direction of the woods. To be sure there was a stretch of uneven and marshy ground to be travelled over before the shelter of the trees could be reached; but a person driven by fear could, at a pinch, travel it in five minutes or less; and a momentary calculation on the part of Mr. Byrd sufficed to show him that more time than this had elapsed from the probable instant of assault to the moment when Mr. Ferris opened the side door and looked out upon the swamp.

The dearth of dwellings on the left-hand side of the street, and, consequently, the comparative immunity from observation which was given to that portion of the house which over-looked the swamp, made him conclude that this outlet from the dining-room had been the one made use of in the murderer’s flight. A glance down the yard to the broken fence that separated the widow’s land from the boggy fields beyond, only tended to increase the probabilities of this supposition, and, alert to gain for himself that full knowledge of the situation necessary to a s............
