"Is that the date?"

"The list is dated 'April, 1760.' The Brigadier Durand has it. It is not written in French."

"Not written in French!" I exclaimed.

"No," replied Fortin solemnly, "it is written in Breton."

"But," I protested, "the Breton language was never written or printed in 1760."

"Except by priests," said the chemist.

"I have heard of but one priest who ever wrote the Breton language," I began.

Fortin stole a glance at my face.

"You mean—the Black Priest?" he asked.

I nodded.
