Dundee led the way up the front stairs to the upper floor, glad to hear the heavy tread of official feet behind him.

"I guess you've got it all doped out who the Selim woman's gentleman friend was," Strawn commented genially, as he followed Dundee into the pleasant, big bedroom.

"I believe I have, but I need Carraway to prove my hunch," Dundee acknowledged.

Eagerly, swiftly, he displayed his first tangible finds—the open windows, the drapes smelling of cigarette smoke, the evening paper of the day before, the faint odor and greasiness of barber's pomade upon the pillow case of the bed which had clearly been slept in since the linen was changed.

"Now, Collins—Harmon—" Dundee whirled upon the two silent plainclothesmen, "I want to know what you saw in these rooms when you searched them early this evening that you don't see now. You looked into the closets and drawers, of course?"

"Yes, sir," Collins answered. "And they was all empty, Dundee. Me and Harmon didn't waste time smelling pillow cases, and I admit we didn't pay no attention to that there newspaper—"

"Empty!" Dundee echoed. "Are you sure?... You, too, Harmon?"

"What are you driving at, boy?" Captain Strawn asked indulgently.

Briefly, with disappointment flattening his voice, Dundee told of his finding the kitchen door ajar, after he had made sure it was locked on his first rounds of the house.

"I worked it out this way," he continued, despite Strawn's grin. "Dexter Sprague was Nita's lover, as I had thought all along. He was in the habit of spending the night here whenever Nita would give him an evening of her company. He was here last night, according to the maid, Lydia Carr. Nita sent her into Hamilton to a picture show. Nita and Sprague quarreled last night, but I am positive he spent the night here anyway. Certainly there was no actual rupture, since Sprague worded his note to her as he did. I have another strong reason for thinking his belongings were here at least until noon today, but that can wait for the moment. Furthermore, I am positive that Sprague descended by the backstairs and went around the house to join the cocktail party which was to follow the hen bridge party."
