About this story
Your firm's gem expert, Czenki, discovers that every leading jeweler in the city received an identical stone the same morning, and the sender, E. van Cortlandt Wynne, summons you all to explain: he claims to control an impossible new supply, and gives the trade one day to buy in. Detectives tail him afterward, and his bag empties itself in full view of them.
How it opens
Harry Latham found an unregistered parcel without a return address among his morning letters.
Mr. FlitcroftNo instruction concerning a loose diamond has reached the company or my desk.
Inside this glazed box lies a blue-white stone finer than any in the firm's vault.
Six carats or a fraction more, perfect in color, and perhaps perfect in cutting.
The expert could not name its mine, owner, or plausible reason for ordinary postage.
Until ownership is established, record every hand that approaches this box.
