the lips of Mrs. Williamson, is due to the positions of the parties as I
have sketched them. Coming behind Mrs. Williamson, unseen therefore, and
from her deafness unheard, the murderer would inflict entire abolition of
consciousness while she was yet unaware of his presence. But with the
servant, who had unavoidably witnessed the attack upon her mistress, the
murderer could not obtain the same fulness of advantage; and _she_
therefore had time for making an agonizing ejaculation.

It has been mentioned, that the murderer of the Marrs was not for nearly a
fortnight so much as suspected; meaning that, previously to the Williamson
murder, no vestige of any ground for suspicion in any direction whatever
had occurred either to the general public or to the police. But there were
two very limited exceptions to this state of absolute ignorance. Some of
the magistrates had in their possession something which, when closely
examined, offered a very probable means for tracing the criminal. But as
yet they had _not_ traced him. Until the Friday morning next after
the destruction of the Williamsons, they had not published the important
fact, that upon the ship-carpenter's mallet (with which, as regarded the
stunning or disabling process, the murders had been achieved) were
inscribed the letters 'J. P.' This mallet had, by a strange oversight on
the part of the murderer, been left behind in Marr's shop; and it is an
interesting fact, therefore, that, had the villain been intercepted by the
brave pawnbroker, he would have been met virtually disarmed. This public
notification was made officially on the Friday, viz., on the thirteenth
day after the first murder. And it was instantly followed (as will be
seen) by a most important result. Meantime, within the secrecy of one
single bedroom in all London, it is a fact that Williams had been
whisperingly the object of very deep suspicion from the very first--that
is, within that same hour which witnessed the Marr tragedy. And singular
it is, that the suspicion was due entirely to his own folly. Williams
