She hesitated, laughed with the ring of hysteria, fluttered into speech.

"You are not, of course, aware of it, but I happen to be an old schoolfellow of your wife's." Her pretty, inquisitive eyes went back to the writing-table, where stood a photograph of Lynette, recently taken—an exquisite, delicate, pearly-toned portrait in a heavy silver-gilt frame. "We used to be great friends. Du Taine was my maiden name. Surely Mrs. Saxham has spoken to you of Greta Du Taine? I left Gueldersdorp at the beginning of the siege. Later, we went to Cape Town. I met my husband there. He is Sir Philip Atherleigh, Baronet." She italicised the word. "He was with his regiment, going to the Front. We were married almost directly. It was a case of love at first sight. Now we are staying at our town house in Werkeley Square. Mrs. Saxham must visit us—my husband is dying to know her."

"I regret that the desire cannot be gratified, madam." The angry blood darkened his face. His tone, even more plainly than his words, told her that the boasted friendship was at an end.

Greta reddened too, and her turquoise-hued eyes dealt him a glance of bitter hatred.

"I did not stay long at the Convent at Gueldersdorp. Nuns are good, simple creatures, and easily imposed upon. And—mother did not wish me to be educated with strays and foundlings—dressed up like young ladies—actually allowed to mingle upon equal terms with them——"

It was Cornelius Agrippa, I think, who once materialised the Devil as an empty purse. The necromancer should have evoked the Spirit of Evil in the shape of a spiteful woman. Greta went on:

"—Such Society as there was, I should say. You were at Gueldersdorp throughout the siege, and for some time before it, I think, Dr. Saxham?"

Two pairs of blue eyes met, the man's hard as shining stones, the woman's dancing with malicious intention. Saxham stiffly bent his head. But her fear of him had evaporated in her triumph. Those inquisitive, turquoise eyes had an excellent memory behind them. Something in the shape of the square black head and hulking shoulders quickened it now.

"It's odd——" Her smile was a grin that showed sharp little white teeth ready to bite, and her speech was pointed with venomed meaning. "I used to go out a great deal in such Society as the place possessed. Yet I do not remember ever having met you!"

Saxham's cold eyes clashed with the malicious turquoises.
