“Finally, having drawn every other cover and picked up no scent, I tried my luck with the housekeeper. Mrs. Lexington is her name — a little, dark, silent person, with suspicious and sidelong eyes. She could tell us something if she would — I am convinced of it. But she was as close as wax. Yes, she had let Mr. McFarlane in at half-past nine. She wished her hand had withered before she had done so. She had gone to bed at half-past ten. Her room was at the other end of the house, and she could hear nothing of what passed. Mr. McFarlane had left his hat, and to the best of her belief his stick, in the hall. She had been awakened by the alarm of fire. Her poor, dear master had certainly been murdered. Had he any enemies? Well, every man had enemies, but Mr. Oldacre kept himself very much to himself, and only met people in the way of business. She had seen the buttons, and was sure that they belonged to the clothes which he had worn last night. The wood-pile was very dry, for it had not rained for a month. It burned like tinder, and by the time she reached the spot, nothing could be seen but flames. She and all the firemen smelled the burned flesh from inside it. She knew nothing of the papers, nor of Mr. Oldacre’s private affairs.

“So, my dear Watson, there’s my report of of a failure. And yet — and yet —” he clenched his thin hands in a paroxysm of conviction— “I know it’s all wrong. I feel it in my bones. There is something that has not come out, and that housekeeper knows it. There was a sort of sulky defiance in her eyes, which only goes with guilty knowledge. However, there’s no good talking any more about it, Watson; but unless some lucky chance comes our way I fear that the Norwood Disappearance Case will not figure in that chronicle of our successes which I foresee that a patient public will sooner or later have to endure.”

“Surely,” said I, “the man’s appearance would go far with any jury?”

“That is a dangerous argument, my dear Watson. You remember that terrible murderer, Bert Stevens, who wanted us to get him off in ‘87? Was there ever a more mild-mannered, Sunday-school young man?”

“It is true.”

“Unless we succeed in establishing an alternative theory, this man is lost. You can hardly find a flaw in the case which can now be presented against him, and all further investigation has served to strengthen it. By the way, there is one curious little point about those papers which may serve us as the starting-point for an inquiry. On looking over the bank-book I found that the low state of the balance was principally due to large checks which have been made out during the last year to Mr. Cornelius. I confess that I should be interested to know who this Mr. Cornelius may be with whom a retired builder has had such very large transactions. Is it possible that he has had a hand in the affair? Cornelius might be a broker, but we have found no scrip to correspond with these large payments. Failing any other indication, my researches must now take the direction of an inquiry at the bank for the gentleman who has cashed these checks. But I fear, my dear fellow, that our case will end ingloriously by Lestrade hanging our client, which will certainly be a triumph for Scotland Yard.”

And, besides, if the parcel had been made up of bulbs, Boxtel knew his neighbour too well not to expect that Van Baerle would not have lost one moment in satisfying his curiosity and feasting his eyes on the present which he had received.

But, on the contrary, Cornelius had received the parcel from the hands of his godfather with every mark of respect, and put it by with the same respectful manner in a drawer, stowing it away so that it should not take up too much of the room which was reserved to his bulbs.

The parcel thus being secreted, Cornelius de Witt got up, pressed the hand of his godson, and turned towards the door, Van Baerle seizing the candlestick, and lighting him on his way down to the street, which was still crowded with people who wished to see their great fellow citizen getting into his coach.

Boxtel had not been mistaken in his supposition. The deposit intrusted to Van Baerle, and carefully locked up by him, was nothing more nor less than John de Witt's correspondence with the Marquis de Louvois, the war minister of the King of France; only the godfather forbore giving to his godson the least intimation concerning the political importance of the secret, merely desiring him not to deliver the parcel to any one but to himself, or to whomsoever he should send to claim it in his name.

And Van Baerle, as we have seen, locked it up with his most precious bulbs, to think no more of it, after his godfather had left him; very unlike Boxtel, who looked upon this parcel as a clever pilot does on the distant and scarcely perceptible cloud which is increasing on its way and which is fraught with a storm.

Little dreaming of the jealous hatred of his neighbour, Van Baerle had proceeded step by step towards gaining the prize offered by the Horticultural Society of Haarlem. He had progressed from hazel-nut shade to that of roasted coffee, and on the very day when the frightful events took place at the Hague which we have related in the preceding chapters, we find him, about one o'clock in the day, gathering from the border the young suckers raised from tulips of the colour of roasted coffee; and which, being expected to flower for the first time in the spring of 1675, would undoubtedly produce the large black tulip required by the Haarlem Society.

On the 20th of August, 1672, at one o'clock, Cornelius was therefore in his dry-room, with his feet resting on the foot-bar of the table, and his elbows on the cover, looking with intense delight on three suckers which he had just detached from the mother bulb, pure, perfect, and entire, and from which was to grow that wonderful produce of horticulture which would render the name of Cornelius van Baerle for ever illustrious.

"I shall find the black tulip," said Cornelius to himself, whilst detaching the suckers. "I shall obtain the hundred thousand guilders offered by the Society. I shall distribute them among the poor of Dort; and thus the hatred which every rich man has to encounter in times of civil wars will be soothed down, and I shall be able, without fearing any harm either from Republicans or Orangists, to keep as heretofore my borders in splendid condition. I need no more be afraid lest on the day of a riot the shopkeepers of the town and the sailors of the port should come and tear out my bulbs, to boil them as onions for their families, as they have sometimes quietly threatened when they happened to remember my having paid two or three hundred guilders for one bulb. It is therefore settled I shall give the hundred thousand guilders of the Haarlem prize to-the poor. And yet ---- "
