Tuppence shook her head.
“The balcony only goes along as far as the boudoir. We were there.”
“He might have slipped out——” suggested Julius.
But Sir James interrupted him.
“Mr. Brown’s methods are not so crude. In the meantime we must send for a doctor, but before we do so, is there anything in this room that might be of value to us?”
Hastily, the three searched. A charred mass in the grate indicated that Mrs. Vandemeyer had been burning papers on the eve of her flight. Nothing of importance remained, though they searched the other rooms as well.
“There’s that,” said Tuppence suddenly, pointing to a small, old-fashioned safe let into the wall. “It’s for jewellery, I believe, but there might be something else in it.”
The key was in the lock, and Julius swung open the door, and searched inside. He was some time over the task.
“Well,” said Tuppence impatiently.
There was a pause before Julius answered, then he withdrew his head and shut to the door.
“Nothing,” he said.
In five minutes a brisk young doctor arrived, hastily summoned. He was deferential to Sir James, whom he recognized.
“Heart failure, or possibly an overdose of some sleeping-draught.” He sniffed. “Rather an odour of chloral in the air.”
Tuppence remembered the glass she had upset. A new thought drove her to the washstand. She found the little bottle from which Mrs. Vandemeyer had poured a few drops.
It had been three parts full. Now—it was empty.
Nothing was more surprising and bewildering to Tuppence than the ease and simplicity with which everything was arranged, owing to Sir James’s skilful handling. The doctor accepted quite readily the theory that Mrs. Vandemeyer had accidentally taken an overdose of chloral. He doubted whether an inquest would be necessary. If so, he would let Sir James know. He understood that Mrs. Vandemeyer was on the eve of departure for abroad, and that the servants had already left? Sir James and his young friends had been paying a call upon her, when she was suddenly stricken down and they had spent the night in the flat, not liking to leave her alone. Did they know of any relatives? They did not, but Sir James referred him to Mrs. Vandemeyer’s solicitor.
Shortly afterwards a nurse arrived to take charge, and the other left the ill-omened building.
“And what now?” asked Julius, with a gesture of despair. “I guess we’re down and out for good.”
Sir James stroked his chin thoughtfully.
“No,” he said quietly. “There is still the chance that Dr. Hall may be able to tell us something.”
“Gee! I’d forgotten him.”
“The chance is slight, but it must not be neglected. I think I told you that he is staying at the Metropole. I should suggest that we call upon him there as soon as possible. Shall we say after a bath and breakfast?”
