Mr. Troy received the earliest intelligence of what was going on.  He wrote at once to communicate his news to Agnes; adding, what he considered to be a valuable hint, in these words: 

’You are intimately acquainted, I know, with Lady Barville, the late Lord Montbarry’s eldest sister.  The solicitors employed by her husband are also the solicitors to one of the two insurance offices.  There may possibly be something in the report of the commission of inquiry touching on Ferrari’s disappearance.  Ordinary persons would not be permitted, of course, to see such a document.  But a sister of the late lord is so near a relative as to be an exception to general rules.  If Sir Theodore Barville puts it on that footing, the lawyers, even if they do not allow his wife to look at the report, will at least answer any discreet questions she may ask referring to it.  Let me hear what you think of this suggestion, at your earliest convenience.’

The reply was received by return of post.  Agnes declined to avail herself of Mr. Troy’s proposal.

‘My interference, innocent as it was,’ she wrote, ’has already been productive of such deplorable results, that I cannot and dare not stir any further in the case of Ferrari.  If I had not consented to let that unfortunate man refer to me by name, the late Lord Montbarry would never have engaged him, and his wife would have been spared the misery and suspense from which she is suffering now.  I would not even look at the report to which you allude if it was placed in my hands—­I have heard more than enough already of that hideous life in the palace at Venice.  If Mrs. Ferrari chooses to address herself to Lady Barville (with your assistance), that is of course quite another thing.  But, even in this case, I must make it a positive condition that my name shall not be mentioned.  Forgive me, dear Mr. Troy!  I am very unhappy, and very unreasonable—­but I am only a woman, and you must not expect too much from me.’

Foiled in this direction, the lawyer next advised making the attempt to discover the present address of Lady Montbarry’s English maid.  This excellent suggestion had one drawback:  it could only be carried out by spending money—­and there was no money to spend.  Mrs. Ferrari shrank from the bare idea of making any use of the thousand-pound note.  It had been deposited in the safe keeping of a bank.  If it was even mentioned in her hearing, she shuddered and referred to it, with melodramatic fervour, as ’my husband’s blood-money!’

So, under stress of circumstances, the attempt to solve the mystery of Ferrari’s disappearance was suspended for a while.
