It was three-quarters of an hour later. District Attorney Sanderson, Captain Strawn and Dundee were alone in the house where Nita "Selim" had been murdered and where her husband had confessed his crimes by committing suicide. The morgue ambulance had come and gone....

"I should have known," Dundee admitted ruefully, as the three men entered Nita's bedroom, "that so ingenious a criminal as Tracey Miles would not have failed to provide against the possibility of discovery. He must have seized an opportunity to spill cyanide of potassium into the decanter when my eyes were off him for a moment—and upon Lois Dunlap."

"I'm glad he did," Sanderson said curtly. "But it was ghastly that poor Lois had to know that it was she, in all innocence, who fired the shot that killed her friend."

"It was," Dundee sighed. "But I believed that the only way I could make Miles confess was to frighten him into thinking Flora would be killed in the same manner.... Well, it worked!"

"Captain Strawn and I are still in the dark as to exactly how Miles managed his wife's murder," Sanderson reminded him. "This morning you chose to tell us nothing more than that a Hamilton man had married Nita Leigh in New York in January, 1918, and that eight years ago, when he saw her picture in The Hamilton Evening Sun, along with the story that 'Anita Lee' had committed suicide, he felt free to marry again.... You said then you knew who the man was but you would not even tell us how you knew—"

"Because I had very little actual proof then," Dundee answered. "As to who he was, the salient clue had been staring me in the face the whole time, but it was not until I was fooling with a set of anagrams last night, idly spelling out the names of all the men who might have married her and then murdered her, that I saw it—"

"Saw what?" Strawn demanded irritably.

"That Selim is simply Miles spelled backwards," Dundee explained. "Possibly because he considered it the sophisticated thing to do, Miles used an assumed name at the party at which he met Nita Leigh—and married her under that name shortly afterward. Even the first name, 'Mat', by which she knew him, was only his initials reversed."

"Simple—but clever," Sanderson commented.
