Below him Colliver was climbing up, knife in mouth, and was already within a couple of yards of him.

I fired and missed, but alarmed Kelly, who jumped up and seized a block which he had cut off to defend himself with.

At the same moment Railton and Rogerson made for me.

As I retreated down the ladder I stumbled, the gun went off and I think hit Rogerson, who was first.

We rolled down the stairs together, he on top and hacking at me furiously with a knife.
