In writing this book, my aim has been to give a true picture in outline of the Slave Trade as it exists at the present time on the east coast of Africa. In order to do this I have selected from the most trustworthy sources what I believe to be the most telling points of "the trade," and have woven these together into a tale, the warp of which is composed of thick cords of fact; the woof of slight lines of fiction, just sufficient to hold the fabric together. Exaggeration has easily been avoided, because-as Dr Livingstone says in regard to the slave-trade-"exaggeration is impossible."
