That never happened, for a reason which we on “The Rising Sun” were quick to see.

In the top-floor room of the anarchists’ house we observed a gas jet burning, and presently some of us noticed the white ash of burnt paper fluttering out of a chimney pot.

“They’re burning documents,” said one of my friends.

They were burning more than that. They were setting fire to the house, upstairs and downstairs. The window curtains were first to catch alight, then volumes of black smoke, through which little tongues of flame licked up, poured through the empty window frames. They must have used paraffin to help the progress of the fire, for the whole house was burning with amazing rapidity.

“Did you ever see such a game in London!” exclaimed the man next to me on the roof of the public house.

For a moment I thought I saw one of the murderers standing on the window sill. But it was a blackened curtain which suddenly blew outside the window frame and dangled on the sill.

A moment later I had one quick glimpse of a man’s arm with a pistol in his hand. He fired and there was a quick flash. At the same moment a volley of shots rang out from the Guardsmen opposite. It is certain that they killed the man who had shown himself, for afterward they found his body (or a bit of it) with a bullet through the skull. It was not long afterward that the roof fell in with an upward rush of flame and sparks. The inside of the house from top to bottom was a furnace.

The detectives, with revolvers ready, now advanced in Indian file. One of them ran forward and kicked at the front door. It fell in, and a sheet of flame leaped out.... No other shot was fired from within. Peter the Painter and his fellow bandits were charred cinders in the bonfire they had made.

So ended the “Battle of Sidney Street,” which created intense excitement and indignation throughout England, and threw a glare of publicity on to the secret haunts of the foreign anarchists in London.

I was one of those who directed the searchlight, for the very next day, with Eddy, my colleague, I took up residence at 62 Sidney Street, and explored the underworld of Whitechapel and the Anarchist clubs of the Russian and German Jews, who were the leading spirits of a philosophy which is now known as Bolshevism. And in that quest I had some strange adventures, and met some very queer folk.
