“That is one result of the explosion,” interrupted the Minister. “You are aware that we have in our shrapnels similar cases of rupture. It is quite possible the initial explosion took place in this chest. Has it been kept?”

“It was handed over to the Government agent.”

“We may need it again when we undertake an analysis of the substances which occasioned the deflagration. Finish your explanations. What became of the carriage stationed in front of the door?”

“The carriage must have left before the accident. There was not a trace of it on the road near the villa. The customs officers, on being interrogated, declared that a brougham, driven by two horses, returned to Paris about eleven o’clock. To the question, ‘Have you anything to declare?’ a female voice had replied, ‘Nothing.’ As for the explosion, the guard at the fort reports that it took place about three o’clock in the morning.”

“Then the man with the foreign accent had remained, after the departure of the carriage?”

“Most probably.”

“You are not certain?”

“I did not wait for the end of the investigations; I came away to inform you of what I had learnt, leaving behind me our agent, with orders to return here at once, after the final statement had been made.”

“Perhaps he is here now?”

Colonel Vallenot pressed the electric knob, and the usher appeared.
