“I see your point. I’ll find out what I can.”
“Then there’s the telephone message. It is not very difficult to imitate a man’s voice over the telephone; but I doubt if the murderer would have risked it unless he had known the man he was imitating pretty well. He may even have been something of a mimic. The idea of imitating the voice would have occurred to such a man. Find out if there is any one connected with the Brooklyns who is much of a mimic.”
“Why, old Sir Vernon Brooklyn used to be the finest impersonator in England in his younger days, before he took to serious acting.”
“I was not thinking of him. There may be others. That sort of talent often runs in families.”
“I’ll make inquiries.”
“Now I come to a much more important point. When one man takes elaborate measures to get another hanged, it usually means he has either some violent grudge, or some strong reason for securing the removal of that particular person. If the murderer tried to get Walter Brooklyn hanged, when he might apparently have got away without leaving any clue at all, he must have had either a violent hatred, or, more probably, a very strong motive for wishing Walter Brooklyn out of the way. We have to find out who had such a motive.”
“Motive seems a dangerous line to go on. You remember that Walter Brooklyn had the strongest financial motive for killing his nephews. He gets a pot of the money when Sir Vernon dies.”
“I know he does; but what I want you to find out is who would get the money if Walter Brooklyn were removed. When you found out about the will, did you discover that?”
“No. It seemed quite enough to find out that Brooklyn stood to get it by killing his nephews. So far as I remember, there was nothing in the will to say who would get the money if they all died.”
“That’s a point you must make quite sure of—not merely what is in the will, but who is the next of kin after Walter Brooklyn. It may be the decisive clue.”
