This book is a welcome addition to the growing corpus of studies of the suppression of slavery during the colonial period. It differs from others in its specific focus on the issue of slave-trading, rather than the institution of slavery. . . .Afigbo makes good use of records of prosecutions of alleged slave-dealers to illustrate the detailed workings of the trade, including the practice of concealing the aquisition and transfer of female slaves under the guise of marriage transactions, and the use of ritual sanctions to discourage escapes and ensure the silence of witnesses.
