may well start, Mr. Troy! It almost
takes you off your guard, doesn't it? Make your mind easy, sir; I
shall find the proof that everybody asks me for in her guilty face.
Let her only change colour by the shadow of a shade--let her eyes only
drop for half an instant--I shall discover her! The one thing I want
to know is, does the law permit it?'

'The law permits it,' Mr. Troy answered gravely; 'but whether her
ladyship will permit it, is quite another question. Have you really
courage enough, Mrs. Ferrari, to carry out this notable scheme of
yours? You have been described to me, by Miss Lockwood, as rather a
nervous, timid sort of person--and, if I may trust my own observation,
I should say you justify the description.'

'If you had lived in the country, sir, instead of living in London,'
Mrs. Ferrari replied, 'you would sometimes have seen even a sheep turn

CHAPTER X

In the mean time, Mrs. Ferrari held to her resolution. She went
straight from Mr. Troy's office to Newbury's Hotel.

Lady Montbarry was at home, and alone. But the authorities of the
hotel hesitated to disturb her when they found that the visitor
declined to mention her name. Her ladyship's new maid happened to
cross the hall while the matter was still in debate. She was a
Frenchwoman, and, on being appealed to, she settled the question in the
swift, easy, rational French way. 'Madame's appearance was perfectly
respectable. Madame might have reasons for not mentioning her name
which Miladi might approve. In any case, there being no orders
forbidding the introduction of a strange lady, the matter clearly
rested between Madame and Miladi. Would Madame, therefore, be good
enough to follow Miladi's maid up the stairs?'

In spite of her res
