When the excitement that greeted this revolutionary reading of the case had died down, Roger went on to defend his theory in more detail.
“It is something of a shock, of course, to find oneself contemplating Bendix as the very cunning murderer of his own wife, but really, once one has been able to rid one’s mind of all prejudice, I don’t see how the conclusion can possibly be avoided. Every item of evidence, however minute, goes to support it.”
“But the motive!” ejaculated Mrs. Fielder-Flemming.
“Motive? Good heavens, he’d motive enough. In the first place he was frankly—no, not frankly; secretly!—tired of her. Remember what we were told of his character. He’d sown his wild oats. But apparently he hadn’t finished sowing them, because his name has been mentioned in connection with more than one woman even since his marriage, usually, in the good old-fashioned way, actresses. So Bendix wasn’t such a solemn stick by any means. He liked his fun. And his wife, I should imagine, was just about the last person in the world to sympathise with such feelings.
“Not that he hadn’t liked her well enough when he married her, quite possibly, though it was her money he was after all the time. But she must have bored him dreadfully very soon. And really,” said Roger impartially, “I think one can hardly blame him there. Any woman, however charming otherwise, is bound to bore a normal man if she does nothing but prate continually about honour and duty and playing the game; and that, I have on good authority, was Mrs. Bendix’s habit.
“Just look at the ménage in this new light. The wife would never overlook the smallest peccadillo. Every tiny lapse would be thrown up at him for years. Everything she did would be right and everything he did wrong. Her sanctimonious righteousness would be forever being contrasted with his vileness. She might even work herself into the state of those half-mad creatures who spend the whole of their married lives reviling their husbands for having been attracted by other women before they even met the girl it was their misfortune to marry. Don’t think I’m trying to blacken Mrs. Bendix. I’m just showing you how intolerable life with her might have been.
“But that’s only the incidental motive. The real trouble was that she was too close with her money, and that too I know for a fact. That’s where she sentenced herself to death. He wanted it, or some of it, badly (it’s what he married her for), and she wouldn’t part.
“One of the first things I did was to consult a Directory of Directors and make a list of the firms he’s interested in, with a view to getting a confidential report on their financial condition. The report reached me just before I left my rooms. It told me exactly what I expected—that every single one of those firms is rocky, some only a little but some within sight of a crash. They all need money to save them. It’s obvious, isn’t it? He’s run through all his own money, and he had to get more. I found time to run down to Somerset House and again it was as I expected: her will was entirely in his favour. The really important point (which no one seems to have suspected) is that he isn’t a good business-man at all; he’s a rotten one. And half-a-million . . . Well!
“Oh, yes. There’s motive enough.”
“Motive allowed,” said Mr. Bradley. “And the nitrobenzene? You said, I think, that Bendix has some knowledge of chemistry.”
