Aladdin of London by Max Pemberton

Alban Kennedy, the impoverished son of a British parson, takes up his abode in the Whitechapel district of London, where he falls in love with a little Polish maid who is infinitely above her mean environment. The circumstances which lead to his adoption by a millionaire, the net of intrigue woven about him, and the efforts to bring about the death of his little sweetheart for political purposes, using him as the innocent tool keeps the reader guessing.
