On reaching the street, they crossed Ludgate Circus, and directed their steps towards Hatton Garden by way of St. Bride Street.

A few minutes later, they emerged in that portion of Holborn which is graced by the mounted statue of a dead German prince acknowledging his lifelong obligations to British hospitality by raising his plumed hat to the London City & Midland Bank on the Viaduct corner. Hatton Garden, as every Londoner knows, begins on the other side of this improving spectacle—a short broad street which disdains to indicate by external opulence the wealth hidden within its walls, though, to an eye practised in London ways, there is a comforting suggestion of prosperity in its wide flagged pavements, comfortable brick buildings, and Jewish names which appear in gilt lettering on plate-glass windows.

Colwyn walked quickly along, glancing at the displayed names. He had almost reached the Clerkenwell end of the Garden when his eye was caught by the name of "Austin Wendover, Dealer in Oriental Stones," gleaming in white letters on the blackboard indicator of a set of offices hived in a building on the corner of a side street. It was the name of the man he was searching for. He turned into the passage, and mounted the stairs. Caldew followed him.

On the landing of the first floor another and smaller board gave the names of those tenants whose offices were at the back of the building. Mr. Wendover's was amongst them, and a pointing hand opposite it revealed that he conducted his business at the end of a long passage with a bend in the middle. When this passage was traversed, Mr. Wendover's name was once more seen, this time on a door, with a notice underneath inviting the visitor to enter without knocking.

Within, a young Jew with a sensual face was busily writing at a desk in the corner, with his back to the door. He ceased and turned around at the sound of the opening door, and, thrusting his fountain pen behind an ear already burdened with a cigarette, waited to be informed what the visitors wanted.

"Is Mr. Wendover in?" Colwyn inquired.

"Yes, he is. What name, please?" The young Jew scrambled down from his stool preparatory to carrying a message.

In answer Colwyn tendered Musard's card of introduction. The young Jew scanned it, shot an appraising glance at the two detectives, and vanished into an inner room. He reappeared swiftly in the doorway, and beckoned them to enter.

The inner room was furnished with leather chairs, a good carpet, and a large walnut table. Mining maps and framed photographs of famous diamonds hung on the walls, but there was nothing about the man seated at the table to suggest association with precious stones except the gleam of his small grey eyes, which were as hard and glistening as the specimen gems in the showcase at his elbow. His face was long, thin and yellow, of a bilious appearance. His gaunt frame was clothed in black, and his low white collar ended in front in two linen tags, fastened with a penny bone stud instead of the diamond which might have been expected. This device, besides dispensing with a necktie, revealed the base of a long scraggy neck, with a tuft of grey hair pushing its way up from below and falling over the interstice of the collar, matching a similar tuft which dangled pendulously from the diamond merchant's nether lip. Altogether, as Mr. Austin Wendover sat at his table with his long yellow hands clasped in front of him waiting for his visitors to announce their business, he looked not unlike a Methodist pastor about to say grace, or a Garden City apostle of culture for the masses preparing to receive a vote of thanks for a lecture on English prose at a workers' mutual improvement society. Even his name suggested, to the serious mind, the compiler of an anthology of British war poets or the writer of a book of Nature studies, rather than the material wealth, female folly, late suppers, greenrooms, frivolity and immorality brought before a vivid imagination by the mere mention of the word diamonds.

"My name is Colwyn; my friend is Detective Caldew, of Scotland Yard," said Colwyn, in response to Mr. Wendover's glance of interrogation. "We are in search of a little information, which we trust you will give us."
