of limiting the authority of the Regent.

Argenson had often during the late reign, and sometimes since, made use
of an intelligent and clever fellow, just suited to him, and named
Pomereu, to make discoveries, arrest people, and occasionally keep them a
short time in his own house. The Parliament believed, and rightly, that
in arresting this man under other pretexts, it would find the thread of
many curious and secret tortuosities, which would aid its design, and
that it might plume itself upon protecting the public safety against the
tyranny of secret arrests and private imprisonments. To carry out its
aim it made use of the Chamber of justice, so as to appear as little as
possible in the matter. This Chamber hastened on so well the
proceedings, for fear of being stopped on the road, that the first hint
people had of them was on learning that Pomereu was, by decree of this
Chamber, in the prisons of the Conciergerie, which are those of the
Parliament. Argenson, who was informed of this imprisonment immediately
it took place, instantly went to the Regent, who that very moment sent a
'lettre de cachet', ordering Pomereu to be taken from prison by force if
the gaoler made the slightest difficulty in giving him up to the bearers
of the 'lettre de cachet'; but that gentleman did not dare to make any.
The execution was so prompt that this man was not an hour in prison, and
they who had sent him there had not time to seize upon a box of papers
which had been transported with him to the Conciergerie, and which was
very carefully carried away with him. At the same time, everything in
any way bearing upon Pomereu, or upon the things in which he had been
employed, was carefully removed and secreted.

The vexation of the Parliament upon seeing its prey, which it had
reckoned upon making such a grand use of, carried off before its eyes,
may be imagined. It left nothing undone in order to move the public by
its complaints, and by its cries against such an attack upon law. The
Chamber of justice sent a deputation to the Regent, who made, fun of it,
by gravely giving permission to the deputies to re-take their prisoner,
but without saying a single word to them upon his escape from gaol. He
was in Paris, in a place where he feared nobody. The Chamber of justice
felt the derisiveness of the Regent's permission, and ceased to transact
business. It thought to embarrass the Regent thus, but 'twould have been
at its own expense.
