And a couple of minutes later, with our lamps glaring, we had turned out upon the broad highway and were travelling at a full forty miles an hour upon the high road to Leicester.

What could it all mean? My master and his companion seemed on the most friendly terms with the spy.

Ten miles from the lodge-gates of Edgcott at a cross-road we picked up an ill-dressed man whom I recognised as the Baptist missionary, Richard Raven, and with the Honourable Bob at my side directing me we tore on through the night, traversing numberless by-roads, until at dawn I suddenly recognised that we were on the North Road, close to Codicote.

A quarter of an hour later we had run the car round to the rear of Shand's pretty rose-embowered cottage, and all descended.

I made excuse to the Honourable Bob that the screw top of the radiator was missing, whereupon von Rausch laughed heartily, and picking up a piece of wire from the bench he bent it so as to form a hook, and with it fished down in the hot water inside.

His companions stood watching, but judge my surprise when I saw him of a sudden draw forth a small aluminium cylinder, the top of which he screwed off and from it took out a piece of tracing-linen tightly folded.

This he spread out, and my quick eyes saw that it was a carefully drawn tracing of a portion of the new type of battleship of the Neptune class (the improved Dreadnought type), with many marginal notes in German in a feminine hand.

In an instant the astounding truth became plain to me. The Baronne, who was in von Rausch's employ, had no doubt surreptitiously obtained the original from Mr. Henry Seymour's despatch-box, it having been sent down to him to Edgcott for his approval.

A most important British naval secret was, I saw, in the hands of the clever spies of the Kaiser!

I made no remark, for in presence of those men was I not helpless?
