"A very interesting case, Inspector," said Wessex, glancing at Harley. "I have not examined the body yet, but I understand that it was a clean wound through the head."
"The bullet entered at the juncture of the nasal and frontal bones," explained Harley, rapidly, "and it came out between the base of the occipital and first cervical. Without going into unpleasant surgical details, the wound was a perfectly _straight_ one. There was no ricochet."
"I understand that a regulation rifle was used?"
"Yes," said Inspector Aylesbury; "we have it."
"And at what range did you say, Inspector?"
"Hundred yards or less," said Wessex, musingly; "and the obstruction met with in the case of a man shot in that way would be--" He looked towards Paul Harley.
"Less than if the bullet had struck the skull higher up," was the reply. "It passed clean through."
"Therefore," continued Wessex, "I am waiting to hear, Inspector, where you found the bullet lodged?"
"Eh?" said the Inspector, and he slowly turned his prominent eyes in Harley's direction. "Oh, I see. That's why you wanted to examine the Tudor garden, is it?"
The face of Inspector Aylesbury grew very red.
"I had deferred looking for the bullet," he explained, "as the case was already as clear as daylight. Probably Mr. Harley has discovered it."
"Is it the regulation bullet?" asked Wessex.
"It is. I found it embedded in one of the yew trees."
"There you are!" exclaimed Aylesbury. "There isn't the ghost of a doubt."
Wessex looked at Harley in undisguised perplexity.
"I must say, Mr. Harley," he admitted, "that I have never met with a clearer case."
"Neither have I," agreed Harley, cheerfully. "I am going to ask Inspector Aylesbury to return here after nightfall. There is a little experiment which I should like to make, and which would definitely establish my case."
"You are not going to tell me that you still persist in believing Camber to be innocent?"
"Not at all. I am merely going to ask you to return at nightfall to assist me in this minor investigation."
"If you ask my opinion," said the Inspector, "no further evidence is needed."
"I don't agree with you," replied Harley, quietly. "Whatever your own ideas upon the subject may be, I, personally, have not yet discovered one single piece of convincing evidence for the prosecution of Camber."
