“We have a gadfly behind us,” said Carlos. “I will not leave till the day after to-morrow. That Contenson is certainly the man who sent the porter after us from the Rue Taitbout; we must ascertain whether this sham Englishman is our foe.” At noon Mr. Samuel Johnson’s black servant was solemnly waiting on his master, who always breakfasted too heartily, with a purpose. Peyrade wished to pass for a tippling Englishman; he never went out till he was half-seas over. He wore black cloth gaiters up to his knees, and padded to make his legs look stouter; his trousers were lined with the thickest fustian; his waistcoat was buttoned up to his cheeks; a red scratch wig hid half his forehead, and he had added nearly three inches to his height; in short, the oldest frequenter of the Cafe David could not have recognized him. From his squarecut coat of black cloth with full skirts he might have been taken for an English millionaire. Contenson made a show of the cold insolence of a nabob’s confidential servant; he was taciturn, abrupt, scornful, and uncommunicative, and indulged in fierce exclamations and uncouth gestures. Peyrade was finishing his second bottle when one of the hotel waiters unceremoniously showed in a man in whom Peyrade and Contenson both at once discerned a gendarme in mufti. “Monsieur Peyrade,” said the gendarme to the nabob, speaking in his ear, “my instructions are to take you to the Prefecture.” Peyrade, without saying a word, rose and took down his hat. “You will find a hackney coach at the door,” said the man as they went downstairs. “The Prefet thought of arresting you, but he decided on sending for you to ask some explanation of your conduct through the peace-officer whom you will find in the coach.” “Shall I ride with you?” asked the gendarme of the peace-officer when Peyrade had got in. “No,” replied the other; “tell the coachman quietly to drive to the Prefecture.” Peyrade and Carlos were now face to face in the coach. Carlos had a stiletto under his hand. The coach-driver was a man he could trust, quite capable of allowing Carlos to get out without seeing him, or being surprised, on arriving at his journey’s end, to find a dead body in his cab. No inquiries are ever made about a spy. The law almost always leaves such murders unpunished, it is so difficult to know the rights of the case.
