I took the road viâ Rouen as the best, though there is a shorter cut, and about two kilometres beyond the quaint old city, just as it was getting light, I got a puncture on the off back tyre. A horse-nail it proved, and in twenty minutes I was on the road again, running at the highest speed I dared along the Seine valley towards Paris. The wind had dropped with the dawn, and the snow-clouds had dispersed with the daybreak. Though grey and very cheerless at first, the wintry sun at last broke through, and it was already half-past seven when, avoiding Paris, I had made a circuit and joined the Fontainebleau road at Charenton, south of the capital.

I glanced at the clock. I had still half an hour to do nearly thirty miles. So, anxious to meet the mysterious Pierrette, I let the car rip, and ran through Melun and the town of Fontainebleau at a furious pace, which would in England have certainly meant the endorsement of my licence.

At the end of the town of Fontainebleau, a board pointed to Marlotte—that tiny river-side village so beloved by Paris artists in summer—and I swung into a great, broad, well-kept road, cut through the bare Forest, with its thousands of straight lichen-covered tree trunks, showing grey in the faint yellow sunlight.

Those long, broad roads through the Forest are, without exception, excellently kept, and there being no traffic, I put on all the pace I dared—a speed which can be easily imagined when one drives a sixty “Mercedes.” Suddenly, almost before I was aware of it, I had flashed across a narrower road running at right angles, and saw, standing back out of the way of the car, a female figure.

In a moment I put on the brakes, and, pulling up, glanced back.

The woman was walking hurriedly towards me, but she was surely not the person of whom I was in search.

She wore a blue dress and a big white-winged linen headdress.

She was a nun!

I glanced around, but there was no other person in sight. We were in the centre of that great historic Forest wherein Napoleon the Great loved to roam alone and think out fresh conquests.
