One last try:

“Hilda! Just listen to me a minute. Look here, you don’t know where I’ve been all this week, do you?”

“I don’t want to know where you’ve been. I know what you’ve been doing. That’s quite enough for me.”

“But dash it—”

Quite useless, of course. She’d found me guilty and now she was going to tell me what she thought of me. That might take her a couple of hours. And after that there was further trouble looming up, because presently it would occur to her to wonder where I’d got the money for this trip, and then she’d discover that I’d been holding out on her about the seventeen quid. Really there was no reason why this row shouldn’t go on till three in the morning. No use playing injured innocence any longer. All I wanted was the line of least resistance. And in my mind I ran over the three possibilities, which were:

A. To tell her what I’d really been doing and somehow make her believe me.

B. To pull the old gag about losing my memory.

C. To let her go on thinking it was a woman, and take my medicine.

But, damn it! I knew which it would have to be.
