In the midst of this general doubt, as none ventured to congratulate another, and all waited in silence, a letter stuck on a spearpoint was seen thrust through a loophole.

Between the despatch and the besiegers was the great moat deep and wide and full of water.

Billet called for a plank, but three were too short, and the fourth, while long enough, was ill adjusted. Still he balanced himself as well as he could and unhesitatingly risked himself on the bending bridge.

All in dumbness fixed their eyes on the man who seemed suspended over the stagnant water, while Pitou, quivering, sat on the brink and hid his face.

All of a sudden, when Billet was two-thirds over, the plank shifted, and throwing up his arms he fell in the moat where he sank out of sight.

Pitou uttered a roar and dived after his master like a Newfoundland dog.

A man went right out on the plank, without hesitation, choosing the same road as Billet: it was Stanislas Maillard, the prison clerk. On reaching the point beneath which he saw two men struggling, he looked, but seeing that they could swim ashore, he continued his way.

In half a minute he was across and took the letter off the pike.

With the same tranquil nerve and steadiness of gait, he passed back over the plank.

But at the very second when all crowded round him to read the message, a hail of bullets rained down from the battlements at the same time as a tremendous report was heard.
