untoward

江戸川乱歩の短編小説 'Two Crippled Men'を読んでいます。夢遊病だと言われた男が又いつ夢遊病を発症して何か問題を起こすのではと心配しています。
The days dragged on, every daylight hour like a century of agony; yet they were nothing compared to the tortures that awaited me at night. Fearing the unknown, I dared not sleep except in snatches. At last, however, a whole month had passed without a single untoward incident, and I began to feel somewhat reassured. "Maybe the doctor was right after all," I told myself. "If I can just stop worrying, I'll be fine."

hard up

江戸川乱歩の短編小説集を読み始めました。九つの短編で構成されていますが、最初に 'The Psychological Test' からの引用します。

Saito was a quiet student of about the same age as Fukiya, and likewise hard up for money.

この "hard up" はここだけではお金に厳しいのか、金欠なのか分かりませんが、この後に殺人事件があり、次の様に出てきました。
Knowing that she had that money hidden in the tree pot, could he not have committed the crime? I also wish to remind you, gentleman of the court, that Fukiya has always been notorious for being financially hard up!"

お金に困って家主を殺したと疑われている状況なので、 "hard up" の意味はお金がないですね。辞書で確認します。

・Collins Dictionary: If you are hard up, you have very little money.: Her parents were very hard up.
