When was that?'

`The time he arrived? Somewhere about twenty minutes past one, I believe; I wasn't here…. Dalrye, my secretary, drove me from the middle of town in my car, and we got here at precisely, two-thirty. We drove along Water Lane… this road.. and Dalrye let me out at the gate of the Bloody Tower, directly opposite us.'

They peered into the gloom. The gate of the Bloody Tower was in the inner ballium wall, facing them across the road. They could see the teeth of the raised portcullis over it, and beyond, a gravelled road which led up to higher ground.

'My own quarters are in the King's House, inside that wall. I was just inside the gate, and Dalrye was driving off down Water Lane to put the car away, when I remembered that I had to speak to Sir Leonard Haldyne.'

Sir Leonard Haldyne?'

`The Keeper of the Jewel House. He lives on the other side of St Thomas's Tower. Turn on your light, please; now move it over to the right, just at the side of Traitors' Gate arch… There, The misty beam showed a heavy iron-bound door sunk in the thick wall. `That leads to a staircase going up to the oratory, and Sir Leonard's quarters are on the other side.

'By this time, in addition to the fog, it was raining. I came across Water Lane, and took hold of the railing here in front of the steps to guide me over to the door. What made me look down I don't know. Anyhow, I did glance down. I couldn't see anything clearly, but by what I did see I knew something was wrong. I climbed over the railing, went down cautiously, and struck a match. I found him.'

`What did you do then?'

It was obviously murder,' the general continued, without seeming to notice the question. 'A man who stabs himself can't drive a steel bolt through his own chest so far that the point comes out under his shoulder-blade; certainly not such a small and weak person as young Driscoll. And he had clearly been dead for some time… the body was growing cold.

`Young Dalrye was coming back from the garage then, and I hailed him. I didn't tell him who the dead man was. He's engaged to Sheila Bitton, and well, you shall hear. But I told him to send one of the warders for Dr Benedict.
