“If the man on duty saw any removing vans in the evening, he would certainly report it,” the constable added politely, and Barclay then went in the direction he indicated.

A quarter of an hour later he stood in the police-office, while the inspector turned over the leaves of the big book in which reports of every untoward or suspicious occurrence are entered for reference, in case of civil actions or other eventualities.

At first he could find nothing, but at last he exclaimed:

“There’s something here. I suppose this is it. Listen: P.C. Baldwin, when he came off duty, reported to the station-sergeant that two large pantechnicon vans and a small covered van of Harmer’s Stores, Knightsbridge, drove up at 8:10 to Number 127a, Cromwell Road, close to Queen’s Gate Gardens, and with seven men and a foreman removed the whole of the furniture. The constable spoke to the foreman, and learned that it was a sudden order given by the householder, a Dr Petrovitch, a foreigner, for his goods to be removed before half-past ten that night, and stored at the firm’s depository at Chiswick.”

“But they must have done it with marvellous alacrity!” Max remarked, at the same time pleased to have so quickly discovered the destination of the Doctor’s household goods.

“Bless you, sir,” answered the inspector, “Harmer’s can do anything. They’d have sent twenty vans and cleared out the place in a quarter of an hour if they’d contracted to do so. You know they can do anything, and supply anything from a tin-tack to a live monkey.”

“Then they’ve been stored at Chiswick, eh?”

“No doubt, sir. The constable would make all inquiry. You know Harmer’s place at Chiswick, not far from Turnham Green railway station? At the office in Knightsbridge they’d tell you all about it. This foreign doctor was a friend of yours, I suppose?”

“Yes, a great friend,” replied Barclay. “The fact is, I’m much puzzled over the affair. Only late this afternoon I was in his study, smoking and talking, but he told me nothing about his sudden removal.”

“Ah, foreigners are generally pretty shifty customers, sir,” was the officer’s remark. “If you’d seen as much as I have of ’em, when I was down at Leman Street, you’d think twice before you trusted one. Of course, no reflection intended on your friend, sir.”
