"There was foul play, sir!" he said unhesitatingly. "The Baron was a strong healthy man who lived frugally, and though he dealt in millions of francs, yet he was most quiet in his habits, and his boast was that he was never out of bed after half-past ten. Though very rich he devoted nearly half his income yearly to charitable institutions. I know the extent of his contributions to the needy, for I have often seen him draw the cheques." "Well--tell me exactly what happened," I asked. "The affair presents some very puzzling features, sir," he replied. "One morning, while dressing, my master told me that he had to motor to The Hague as he wished to meet in strict secrecy a man who would call to see him at a little hotel called the Rhijn, in the Oranje Straat. He asked me to drive him there so that Mullard, the chauffeur, should have no knowledge of the visit. This I promised to do, for I can drive a car. We arrived early in the afternoon, and the Baron, who was unknown at the obscure little place, ordered lunch for us both. He ate his in the private room he had engaged, and at about three o'clock the visitor arrived. He inquired of the proprietor and was shown into the Baron's private room. I judged him to be about forty, of middle height, well-dressed, and wearing big round tortoiseshell glasses, like those Americans so often wear. He was red-faced and walked with a slight limp." "And what happened while your master was with the stranger?" "The Baron came out and told me to go to the garage with the car, and I was telephoned for an hour later. When I met him again he seemed to be in an ill and petulant mood, for he told me to drive back to Amsterdam with all speed. He also again made me promise to tell nobody of the secret meeting." "And then?" I asked anxiously. "On arrival home he washed, dressed, and dined alone. Afterwards he put on his gloves, grey suède ones, ready to go, but exchanged them for a pair of white ones, as he recollected that he was going to the opera. Then he walked out to the car, but suddenly cried, 'Oh! My head! My head!' and fell on to the pavement. I was just behind him when he did so, and hurried to get him up. But he was already unconscious, and scarcely before we could get him into the house he expired." "And why do you suspect foul play?" I asked. "I feel certain that my master did not die from natural causes," declared the thin-faced man-servant. "You suspect that the individual in round spectacles had a hand in it--eh?" "I do. But how, I have no idea. The police pooh-pooh my suspicions. But if my suspicions are unfounded, why has not the stranger come forward? There has been a lot about the affair in the papers." "Yes," I said. "It certainly appears strange, for there can be no cause for secrecy now that the Baron is dead, even if some great financial transaction had been involved."
