Seven, Seven, Seven--City

The line I wanted was strung aloft at some point of its length, but where did it leave the subway and how could I recognise it when found?

I now did what I ought to have done long before--secured the services of George Reilly, the most expert "trouble-man" in the country. When the whole subject was laid before him he pronounced unequivocally in favour of starting at the City office to run down that wire. A long chase was more likely of success than a short one.
