“We make your Grace our compliments,” said Gaspard. “We are of the household of the Ambassador of Spain, and could not rest indoors when great deeds were being done in the city.”

The young man smiled pleasantly. There was a boyish grace in his gesture.

“You are welcome, gentlemen. I would have every good Catholic in Europe see with his own eyes the good work of this Bartholomew's day. I would ask you to ride with me, but I leave the city in pursuit of the Count of Montgomery, who is rumoured to have escaped. There will be much for you to see on this happy Sunday. But stay! You are not attended, and our streets are none too safe for strangers. Presently the Huguenots will counterfeit our white cross, and blunders may be made by the overzealous.”

He unclasped the jewel which hung at the end of his chain. It was a little Agnus of gold and enamel, surmounting a lozenge-shaped shield charged with an eagle.

“Take this,” he said, “and return it to me when the work is over. Show it if any man dares to question you. It is a passport from Henry of Guise.... And now forward,” he cried to his followers. “Forward for Montgomery and the Vidame.”

The two looked after the splendid figure. “That bird is in fine feather,” said Champernoun.

Gaspard's jaw was very grim. “Some day he will lie huddled under the assassin's knife. He will die as he has made my chief die, and his body will be cast to the dog's.... But he has given me a plan,” and he spoke in his companion's ear.

The Englishman laughed. His stolidity had been slow to quicken, but his eyes were now hot and he had altogether ceased to swear.

“First let me get back to Walsingham's lodging. I have a young kinsman there, they call him Walter Raleigh, who would dearly love this venture.”

“Tut, man, be serious. We play a desperate game, and there is no place for boys in it. We have Guise's jewel, and by the living God we will use it. My mark is Petrucci.”
