William Le Queux,
The Invasion of 1910 — Book II
“ Below those dark buildings in Lothbury and Lombard Street, behind the black walls of the Bank of England, and below every branch bank all over London, were millions in gold and notes, the wealth of the greatest city the world has ever known. The strong rooms were, for the most part, the strongest that modern engineering could devise, some with various arrangements by which all access was debarred by an inrush of water; but, alas! dynamite is a great leveller, and it was felt that not a single strong room in the whole of London could withstand an organised attack by German engineers. ”
