Sodom had no Bible - Ravenhill

I just finished this book today and boy oh boy it is hard hitting. The Title is "Sodom had no Bible" by Leonard Ravenhill.I recommend this book to all:Here is an excerpt:"Why are our feet so leaden in moving to the rescue of those who move relentlessly by to the edge of eternity, and whose one step into it will seal their doom? Why is there at present amongst us this criminal indifference to the lostness of men? And criminal it is!Have we nothing to communicate? Is our living so inconsistent with our telling? Are we pitiably unsure of the truth of the Bible concerning the lost? Are we so stony-hearted that neither God's promises not God's threats disturb us? What octopus has us in its grip? Where will our spiritual polio, our slovenly attention to divine truth land us--and others?

Our evangelism minister, who met Brother Len (as he called him), also said that that was a great book.

Where could I get a copy of that book? I've heard of it before and would really like to read it, but I haven't found it anywhere. Thanks.
