After about ten minutes a knock came to the door, and the servant entered, carrying a mahogany chest of chemicals, with a small electric battery set on top of it. He placed it on the table, and went out again, returning with a long coil of steel and platinum wire and two rather curiously-shaped iron clamps.
"Shall I leave the things here, sir?" he asked Campbell.
"Yes," said Dorian. "And I am afraid, Francis, that I have another errand for you. What is the name of the man at Richmond who supplies Selby with orchids?"
"Yes,--Harden. You must go down to Richmond at once, see Harden personally, and tell him to send twice as many orchids as I ordered, and to have as few white ones as possible. In fact, I don't want any white ones. It is a lovely day, Francis, and Richmond is a very pretty place, otherwise I wouldn't bother you about it."
"No trouble, sir. At what time shall I be back?"
Dorian looked at Campbell. "How long will your experiment take, Alan?" he said, in a calm, indifferent voice. The presence of a third person in the room seemed to give him extraordinary courage.
Campbell frowned, and bit his lip. "It will take about five hours," he answered.
[93] "It will be time enough, then, if you are back at half-past seven, Francis. Or stay: just leave my things out for dressing. You can have the evening to yourself. I am not dining at home, so I shall not want you."
"Thank you, sir," said the man, leaving the room.
"Now, Alan, there is not a moment to be lost. How heavy this chest is! I'll take it for you. You bring the other things." He spoke rapidly, and in an authoritative manner. Campbell felt dominated by him. They left the room together.
When they reached the top landing, Dorian took out the key and turned it in the lock. Then he stopped, and a troubled look came into his eyes. He shuddered. "I don't think I can go in, Alan," he murmured.
"It is nothing to me. I don't require you," said Campbell, coldly.
Dorian half opened the door. As he did so, he saw the face of the portrait grinning in the sunlight. On the floor in front of it the torn curtain was lying. He remembered that the night before, for the first time in his life, he had forgotten to hide it, when he crept out of the room.
