“I believe Señor Rivero suspects that Sanz is one of a very dangerous gang,” I said. “If so, it would be well to arrest them all.”
“Are the others in London, do you think?” asked the tall, dark-haired official of the Criminal Investigation Department.
“Ah! That I do not know,” was my reply. “I only know that Mateo Sanz is a very dangerous person, who has been wanted for several years.”
“Well, we thank you very much for your information, sir, and we shall act upon it at once,” he replied. And then I went along the stone corridor and out again into Parliament Street, well satisfied that I had, at last, placed one of the criminals in the hands of the police, who would, in due course, learn the true facts concerning Baron van Veltrup’s mysterious end.
CHAPTER THE TWENTY-SEVENTH
A CURIOUS STORY

In the meantime my curiosity was further aroused by a note sent to me by Mrs. Tennison’s servant, Mrs. Alford, next day, saying that Doctor Moroni had called at Longridge Road and that, finding Miss Gabrielle absent, he had put to her a number of questions concerning myself.
