the stone step; but Mary Hennessey had so confused and obliterated
the outlines that now it was impossible accurately to measure them. A
half-burned match was found under the sink,--evidently thrown there
by the burglars. It was of a kind known as the safety-match, which
can be ignited only by friction on a strip of chemically prepared
paper glued to the box. As no box of this description was discovered,
and as all the other matches in the house were of a different make,
the charred splinter was preserved. The most minute examination
failed to show more than this. The last time Mr. Shackford had been
seen alive was at six o'clock the previous evening.

Who had done the deed?

Tramps! answered Stillwater, with one voice, though Stillwater lay
somewhat out of the natural highway, and the tramp--that bitter
blossom of civilization whose seed was blown to us from over
seas--was not then so common by the New England roadsides as he
became five or six years later. But it was intolerable not to have a
theory; it was that or none, for conjecture turned to no one in the
village. To be sure, Mr. Shackford had been in litigation with
several of the corporations, and had had legal quarrels with more
than one of his neighbors; but Mr. Shackford had never been
victorious in any of these contests, and the incentive of revenge was

to half a dozen idlers, and the less frequented streets had resumed
their normal aspect of dullness, there was a strange, electric
quality in the atmosphere. The community was in that state of
suppressed agitation and suspicion which no word adequately
