"Yes," replied Sir Philip dryly, "and I thank God for it."

Whereat the Spanish Ambassador smiled grimly.

Presently he spoke again to the Master of the Rolls. He had been attentively watching the twin brothers, who sat at the table side by side.

"By St. Iago," he said in a low voice, "I have been looking at the twin brothers for the last five minutes, and at this moment I cannot tell you which is William and which is Ralph; I do not think that the world contains another so perfect example of the 'Dioscuroi'; no man could tell them apart."

Sir Philip shivered inwardly at these words, and he thought within himself—

"Does our friendly Ambassador begin to suspect the legal trick by which our case was won? If so, the sooner we get Ralph across the water the better."

At that moment his eye fell upon Don Diego, who sat next to Susan, with whom he was holding eager discourse.

"No, no," thought he, "no harm can come to our twins from that quarter; he can never forget the noble daring that saved his son's life."

As a rule no sound from the outside world ever penetrated the stillness of the dining-hall of Gray's Inn, yet to the watchful ears of some who sat at that festive table it seemed as if armed men were in movement in the great courtyard.

No word of command, no treading of iron-girt men, no clash of arms, but only a dull sense of approaching danger!
