It was here that an alliance of Federal inspectors and police, Malone with them, entered the case. The law had watched the Suydam action with interest, and had in many instances been called upon to aid the private detectives. In this work it developed that Suydam's new associates were among the blackest and most vicious criminals of Red Hook's devious lanes, and that at least a third of them were known and repeated offenders in the matter of thievery, disorder, and the importation of illegal immigrants. Indeed, it would not have been too much to say that the old scholar's particular circle coincided almost perfectly with the worst of the organized cliques which smuggled ashore certain nameless and unclassified Asian dregs wisely turned back by Ellis Island. In the teeming rookeries of Parker Place--since renamed--where Suydam had his basement flat, there had grown up a very unusual colony of unclassified slant-eyed folk who used the Arabic alphabet but were eloquently repudiated by the great mass of Syrians in and around Atlantic Avenue. They could all have been deported for lack of credentials, but legalism is slow-moving, and one does not disturb Red Hook unless publicity forces one to. These creatures attended a tumbledown stone church, used Wednesdays as a dance hall, which reared its Gothic buttresses near the vilest part of the waterfront. Clergy throughout Brooklyn denied the place all standing and authenticity, and policemen agreed with them when they listened to the noises it emitted at night. Malone used to fancy he heard terrible cracked bass notes from a hidden organ far underground when the church stood empty and unlighted, whilst all observers dreaded the shrieking and drumming which accompanied the visible services. Suydam, when questioned, said he thought the ritual was some remnant of Nestorian Christianity tinctured with the Shamanism of Tibet. Most of the people, he conjectured, were of Mongoloid stock, originating somewhere in or near Kurdistan--and Malone could not help recalling that Kurdistan is the land of the Yezidees, last survivors of the Persian devil-worshippers. However this may have been, the stir of the Suydam investigation made it certain that these unauthorized newcomers were flooding Red Hook in increasing numbers; entering through some marine conspiracy unreached by revenue officers and harbor police, overrunning Parker Place and rapidly spreading up the hill, and welcomed with curious fraternalism by the other assorted denizens of the region. Their squat figures and characteristic squinting physiognomies grotesquely combined with flashy American clothing, appeared more and more numerously among the loafers and nomad gangsters of the Borough Hall section; till at length it was deemed necessary to compute their number, ascertain their sources and occupations, and find if possible a way to round them up and deliver them to the proper immigration authorities.
