“Ah, that’s the question,” said Barker.
“At what o’clock was it raised?”
“It was nearly six o’clock,” said Ames, the butler.
“I’ve heard,” said the sergeant, “that it was usually raised at sunset. That would be nearer half-past four than six at this time of year.”
“ Mrs. Douglas had visitors to tea,” said Ames. “I couldn’t raise it until they went. Then I wound it up myself.”
“Then it comes to this,” said the sergeant: “If anyone came from outside— if they did—they must have got in across the bridge before six and been in hiding ever since, until Mr. Douglas came into the room after eleven.”
“That is so! Mr. Douglas went round the house every night the last thing before he turned in to see that the lights were right. That brought him in here. The man was waiting and shot him. Then he got away through the window and left his gun behind him. That’s how I read it; for nothing else will fit the facts.”
The sergeant picked up a card which lay beside the dead man on the floor. The initials V. V. and under them the number 341 were rudely scrawled in ink upon it.
“What’s this?” he asked, holding it up.
Barker looked at it with curiosity. “I never noticed it before,” he said. “The murderer must have left it behind him.”
“ V. V. —341. I can make no sense of that.”
The sergeant kept turning it over in his big fingers. “What’s V. V. ? Somebody’s initials, maybe. What have you got there, Dr. Wood?”
