Read it through once

Thuggee became known to the British authorities in India about 1810, but its wide prevalence was not suspected; it was not regarded as a serious matter, and no systematic measures were taken for its suppression until about 1830. About that time Major Sleeman captured Eugene Sue's Thug-chief, “Feringhea,” and got him to turn King's evidence. The revelations were so stupefying that Sleeman was not able to believe them. Sleeman thought he knew every criminal within his jurisdiction, and that the worst of them were merely thieves; but Feringhea told him that he was in reality living in the midst of a swarm of professional murderers; that they had been all about him for many years, and that they buried their dead close by. These seemed insane tales; but Feringhea said come and see—and he took him to a grave and dug up a hundred bodies, and told him all the circumstances of the killings, and named the Thugs who had done the work. It was a staggering business. Sleeman captured some of these Thugs and proceeded to examine them separately, and with proper precautions against collusion; for he would not believe any Indian's unsupported word. The evidence gathered proved the truth of what Feringhea had said, and also revealed the fact that gangs of Thugs were plying their trade all over India. The astonished government now took hold of Thuggee, and for ten years made systematic and relentless war upon it, and finally destroyed it. Gang after gang was captured, tried, and punished. The Thugs were harried and hunted from one end of India to the other. The government got all their secrets out of them; and also got the names of the members of the bands, and recorded them in a book, together with their birthplaces and places of residence.
