"You are a good fellow. I intend to be very careful in my movements, and, so far as possible, not to let it be known that the house is occupied. I do not wish Barbara to remain. We must find a home for her somewhere, and we must pledge her to secrecy. I would take her to my own house, but at present I do not consider it prudent to do so. My wife is an inquisitive woman, and something might leak out; besides, in order that my time may be perfectly free, I intend to send her into the country for a fortnight; she shall go to-morrow. I can easily find an excuse for not accompanying her. You lodge in a quiet part of London, and you have spoken in praise of your landlady. Would she, for a consideration, give Barbara board and lodging for a little while?"
"No doubt she would. In fact, I think she is looking for a girl to assist her in the house."
"Very well. At what hour in the morning are you due at your office?"
"Half-past nine."
"Then you will be able, if you leave here at about seven or half-past, to take Barbara to Canonbury, and get to the office in time."
"Yes, I can do that, and in the evening I will join you."
"Thanks. The next thing is about your nephew, Ronald. It appears to me to be almost an act of treachery to conceal from him what has occurred."
"What good purpose would be served," asked Bob, "by disclosing it to him? He is blind, and could not assist us. By and by, perhaps, he may be of use, though I do not see in what way; at present it would only distress him to let him into the secret."
"We will wait, then; but I shall call upon him to-morrow and have a little chat with him about Mr. Nisbet. It will be a busy day for all of us, and I shall be absent from the house till evening, but you will find me here when you come. Another thing that is in my mind is whether there is any special motive for Mr. Nisbet's return to London--any special motive, I mean, in relation to this mystery."
"Impossible to say, Ned."
