The terror that sweeps into present day Boston began ages ago in a remote cave in India. There, the cult of Thuggee was born, mingling primal sexuality, worship of the godess Kalie, and ritual murder. More than a hundered years ago the British Raj suppressed the dread cult. But now, when victims of the rumel - the silk scarf knotted into a silent deadly weapon - are found in mass graves, the Indian police fear a new reign of terror.
