“Who shot her？”cried Rogers as he rushed into the hospital three minutes after his ex-wife died from a bullet through her head．
“Just a minute，”Professor Fordney said．“I'd like to ask you a few questions．．．routine ，you know．Although divorced for the past six months，you have been living in the same house with your ex-wife，have you not？”
“That's right．”
“Had any trouble recently？”
“Well．．．yesterday when I told her I was going on a business trip， she threatened suicide．In fact，I grabbed a bottle of iodine（碘酒） from her as she was about to drink it．When I left last evening at seven， however，telling her I was spending the night with friends in Sewickley， she made no objections．Returning to town this afternoon，”he continued，“I called my home and the maid answered．”
“Just what did she say？”
“‘Oh，Mr．Rogers，they took poor mistress to St．Anne's hospital about half an hour ago．Please hurry to her！’She was crying so I couldn't get anything else out of her；then I hurried here．Where is she？”
“The nurse here will direct you，”responded the Professor．“A queer case this is，Joe，”said Inspector Kelley，who had been listening to the conversation．“These moderns are a little too much for me！A man and woman living together after being divorced six months！”
“A queer case，indeed，Jim，” sighed Fordney．“You'd better detain（拘留）Rogers．If he didn't shoot her himself，I'm confident he knows who did．”
