Slatius protested his innocence of any such design, and vehemently besought the officer to release him, telling him as a reason for his urgency and an explanation of his unprepossessing aspect—that he was an oculist from Amsterdam, John Hermansen by name, that he had just committed a homicide in that place, and was fleeing from justice.
The honest quartermaster saw no reason why a suspected spy should go free because he proclaimed himself a murderer, nor why an oculist should escape the penalties of homicide. "The more reason," he said, "why thou shouldst be my prisoner." The ex-preacher was arrested and shut up in the state prison at the Hague.
The famous engraver Visser executed a likeness on copper-plate of the grim malefactor as he appeared in his boor's disguise. The portrait, accompanied by a fiercely written broadsheet attacking the Remonstrant Church, had a great circulation, and deepened the animosity against the sect upon which the unfrocked preacher had sworn vengeance. His evil face and fame thus became familiar to the public, while the term Hendrik Slaet became a proverb at pot-houses, being held equivalent among tipplers to shirking the bottle.
Korenwinder, the treasurer of the association, coming to visit Stoutenburg soon after van Dyk had left him, was informed of the discovery of the plot and did his best to escape, but was arrested within a fortnight's time.
Stoutenburg himself acted with his usual promptness and coolness. Having gone straightway to his brother to notify him of the discovery and to urge him to instant flight, he contrived to disappear. A few days later a chest of merchandise was brought to the house of a certain citizen of Rotterdam, who had once been a fiddler, but was now a man of considerable property. The chest, when opened, was found to contain the Seigneur de Stoutenburg, who in past times had laid the fiddler under obligations, and in whose house he now lay concealed for many days, and until the strictness with which all roads and ferries in the neighbourhood were watched at first had somewhat given way. Meantime his cousin van der Dussen had also effected his escape, and had joined him in Rotterdam. The faithful fiddler then, for a thousand florins, chartered a trading vessel commanded by one Jacob Beltje to take a cargo of Dutch cheese to Wesel on the Rhine. By this means, after a few adventures, they effected their escape, and, arriving not long afterwards at Brussels, were formally taken under the protection of the Archduchess Isabella.
Stoutenburg afterwards travelled in France and Italy, and returned to Brussels. His wife, loathing his crime and spurning all further communication with him, abandoned him to his fate. The daughter of Marnix of Sainte-Aldegonde had endured poverty, obscurity, and unmerited obloquy, which had become the lot of the great statesman's family after his tragic end, but she came of a race that would not brook dishonour. The conspirator and suborner of murder and treason, the hirer and companion of assassins, was no mate for her.
Stoutenburg hesitated for years as to his future career, strangely enough keeping up a hope of being allowed to return to his country.
Subsequently he embraced the cause of his country's enemies, converted himself to the Roman Church, and obtained a captaincy of horse in the Spanish service. He was seen one day, to the disgust of many spectators, to enter Antwerp in black foreign uniform, at the head of his troopers, waving a standard with a death's-head embroidered upon it, and wearing, like his soldiers, a sable scarf and plume. History disdains to follow further the career of the renegade, traitor, end assassin.
When the Seigneur de Groeneveld learned from his younger brother, on the eventful 6th of February, that the plot had been discovered, he gave himself up for lost. Remorse and despair, fastening upon his naturally feeble character, seemed to render him powerless. His wife, of more hopeful disposition than himself and of less heroic mould than Walburg de Marnix, encouraged him to fly. He fled accordingly, through the desolate sandy downs which roll between the Hague and the sea, to Scheveningen, then an obscure fishing village on the coast, at a league's distance from the capital. Here a fisherman, devoted to him and his family, received him in his hut, disguised him in boatman's attire, and went with him to the strand, proposing to launch his pinkie, put out at once to sea, and to land him on the English coast, the French coast, in Hamburg—where he would.
The sight of that long, sandy beach stretching for more than seventy miles in an unbroken, melancholy line, without cove, curve, or indentation to break its cruel monotony, and with the wild waves of the German Ocean, lashed by a wintry storm, breaking into white foam as far as the eye could reach, appalled the fugitive criminal. With the certainty of an ignominious death behind him, he shrank abjectly from the terrors of the sea, and, despite the honest fisherman's entreaties, refused to enter the boat and face the storm. He wandered feebly along the coast, still accompanied by his humble friend, to another little village, where the fisherman procured a waggon, which took them as far as Sandvoort. Thence he made his way through Egmond and Petten and across the Marsdiep to Tegel, where not deeming himself safe he had himself ferried over to the neighbouring island of Vlieland. Here amongst the quicksands, whirlpools, and shallows which mark the last verge of habitable Holland, the unhappy fugitive stood at bay.
