It was the case of Robert Suydam which took Malone to the heart of things in Red Hook. Suydam was a lettered recluse of ancient Dutch family, possessed originally of barely independent means, and inhabiting the spacious but ill-preserved mansion which his grandfather had built in Flatbush when that village was little more then a pleasant group of Colonial cottages surrounding the steepled and ivy-clad Reformed Church with its iron-railed yard of Netherlandish gravestones. In this lonely house, set back from Martense Street amidst a yard of venerable trees, Suydam had read and brooded for some six decades except for a period a generation before, when he had sailed for the Old World and remained there out of sight for eight years. He could afford no servants, and would admit but few visitors to his absolute solitude; eschewing close friendships and receiving his rare acquaintances in one of the three ground-floor rooms, which he kept in order--a vast, high-ceiled library whose walls were solidly packed with tattered books of ponderous, archaic, and vaguely repellent aspect. The growth of the town and its final absorption in the Brooklyn district had meant nothing to Suydam, and he had come to mean less and less to the town. Elderly people still pointed him out on the streets, but to most of the recent population he was merely a queer, corpulent old fellow whose unkempt white hair, stubbly beard, shiny black clothes and gold-headed cane earned him an amused glance and nothing more. Malone did not know him by sight till duty called him to the case, but had heard of him indirectly as a really profound authority on medieval superstition, and had once idly meant to look up an out-of-print pamphlet of his on the Kabbalah and the Faustus legend, which a friend had quoted from memory.
