“Probably the doings of the Harewood Club, which was essentially a gambling club, would for ever have remained ‘officially’ absent from the knowledge of the police authorities but for the murder in the Regent’s Park and the revelations which came to light in connection with it.

“I dare say you know the quiet square which lies between Portland Place and the Regent’s Park and is called Park Crescent at its south end, and subsequently Park Square East and West.  The Marylebone Road, with all its heavy traffic, cuts straight across the large square and its pretty gardens, but the latter are connected together by a tunnel under the road; and of course you must remember that the new tube station in the south portion of the Square had not yet been planned.

“February 6th, 1907, was a very foggy night, nevertheless Mr. Aaron Cohen, of 30, Park Square West, at two o’clock in the morning, having finally pocketed the heavy winnings which he had just swept off the green table of the Harewood Club, started to walk home alone.  An hour later most of the inhabitants of Park Square West were aroused from their peaceful slumbers by the sounds of a violent altercation in the road.  A man’s angry voice was heard shouting violently for a minute or two, and was followed immediately by frantic screams of ‘Police’ and ‘Murder.’  Then there was the double sharp report of firearms, and nothing more.

“The fog was very dense, and, as you no doubt have experienced yourself, it is very difficult to locate sound in a fog.  Nevertheless, not more than a minute or two had elapsed before Constable F 18, the point policeman at the corner of Marylebone Road, arrived on the scene, and, having first of all whistled for any of his comrades on the beat, began to grope his way about in the fog, more confused than effectually assisted by contradictory directions from the inhabitants of the houses close by, who were nearly falling out of the upper windows as they shouted out to the constable.

“‘By the railings, policeman.’

“‘Higher up the road.’

“‘No, lower down.’

“‘It was on this side of the pavement I am sure.’

“No, the other.’

“At last it was another policeman, F 22, who, turning into Park Square West from the north side, almost stumbled upon the body of a man lying on the pavement with his head against the railings of the Square.  By this time quite a little crowd of people from the different houses in the road had come down, curious to know what had actually happened.

“The policeman turned the strong light of his bull’s-eye lantern on the unfortunate man’s face.

“‘It looks as if he had been strangled, don’t it?’ he murmured to his comrade.

“And he pointed to the swollen tongue, the eyes half out of their sockets, bloodshot and congested, the purple, almost black, hue of the face.

“At this point one of the spectators, more callous to horrors, peered curiously into the dead man’s face.  He uttered an exclamation of astonishment.
