“Shocking! shocking!” gasped Boscovitch. “I think—if you don’t mind—I’d—I’d rather not. You don’t think it necessary, doctor, do you?”

“Yes, I do,” replied Thorndyke. “Early identification may be of the first importance.”

“Then I suppose I must,” said Boscovitch; and, with extreme reluctance, he followed the station-master to the lamp-room, as the loud ringing of the bell announced the approach of the boat train. His inspection must have been of the briefest, for, in a few moments, he burst out, pale and awe-stricken, and rushed up to Thorndyke.

“It is!” he exclaimed breathlessly. “It’s Brodski! Poor old Brodski! Horrible! horrible! He was to have met me here and come on with me to Amsterdam.”

“Had he any—merchandize about him?” Thorndyke asked; and, as he spoke, the stranger whom I had previously noticed edged up closer as if to catch the reply.

“He had some stones, no doubt,” answered Boscovitch, “but I don’t know what they were. His clerk will know, of course. By the way, doctor, could you watch the case for me? Just to be sure it was really an accident or—you know what. We were old friends, you know, fellow townsmen, too; we were both born in Warsaw. I’d like you to give an eye to the case.”

“Very well,” said Thorndyke. “I will satisfy myself that there is nothing more than appears, and let you have a report. Will that do?”

“Thank you,” said Boscovitch. “It’s excessively good of you, doctor. Ah, here comes the train. I hope it won’t inconvenience you to stay and see to the matter.”

“Not in the least,” replied Thorndyke. “We are not due at Warmington until tomorrow afternoon, and I expect we can find out all that is necessary to know and still keep our appointment.”

As Thorndyke spoke, the stranger, who had kept close to us with the evident purpose of hearing what was said, bestowed on him a very curious and attentive look; and it was only when the train had actually come to rest by the platform that he hurried away to find a compartment.
