Best biography on William Booth?

Can someone help me? I'm trying to update my library when it comes to good and edifying biographies. I just realized that I do not have anything on William Booth.

Do you know which biography is the best concerning this great man of God?

Thanks! I will download it. Btw: Have you read it yourself?
