"Approximately, two miles. In other words, to A Street northeast."

"Not very far from it."
"Do we go to a house there?"
"Yes; there is a house there which I am making use of for this occasion. There is another one behind it which fronts upon the avenue. The two come almost together at the rear. I shall make use of both houses before we finish."
