Dicky Donovan was of that rare type of man who has the keenest desire to know all things, good or evil, though he was fastidious when it came to doing them. He had a gift of keeping his own commandments. If he had been a six-footer and riding eighteen stone--if he hadn't been, as Fielding often said, so "damned finicky," he might easily have come a cropper. For, being absolutely without fear, he did what he listed and went where he listed. An insatiable curiosity was his strongest point, save one. If he had had a headache--though he never had--he would at once have made an inquiry into the various kinds of headache possible to mortal man, with pungent deductions from his demonstrations. So it was that when he first saw a dancing-girl in the streets of Cairo he could not rest until by circuitous routes he had traced the history of dancing- girls back through the ages, through Greece and the ruby East, even to the days when the beautiful bad ones were invited to the feasts of the mighty, to charm the eyes of King Seti or Queen Hatsu. He was an authority on the tribe of the Ghawazee, proving, to their satisfaction and his own, their descent from the household of Haroon al Rashid. He was, therefore, welcome among them. But he had found also, as many another wise man has found in "furrin parts," that your greatest safety lies in bringing tobacco to the men and leaving the women alone. For, in those distant lands, a man may sell you his nuptial bed, but he will pin the price of it to your back one day with the point of a lance or the wedge of a hatchet. Herebefore will be found the reason why Dicky Donovan--twenty-five and no moustache, pink-cheeked and rosy-hearted, and "no white spots on his liver"--went straight, that particular night, to the house of the chief dancing-girl of Beni Hassan for help in his trouble. From her he had learned to dance the dance of the Ghawazee. He had learned it so that, with his insatiable curiosity, his archaeological instinct, he should be able to compare it with the Nautch dance of India, the Hula-Hula of the Sandwich Islanders, the Siva of the Samoans. A half-hour from the time he set his foot in Beni Hassan two dancing- girls issued from the house of the ghdzeeyeh, dressed in shintiydn and muslin tarah, anklets and bracelets, with gold coins about the forehead --and one was Dicky Donovan. He had done the rare thing: he had trusted absolutely that class of woman who is called a "rag" in that far country, and a "drab" in ours. But he was a judge of human nature, and judges of human nature know you are pretty safe to trust a woman who never trusts, no matter how bad she is, if she has no influence over you. He used to say that the better you are and the worse she is, the more you can trust her. Other men may talk, but Dicky Donovan knows.
