pretty pass

Anthony Horowitz の "The House of Silk" からの引用です。
We left her sitting in misery and Lestrade took his leave. 'I'm sure we'll run into each other again, Mr. Holmes,' he said. 'And if you need me, you know where to find me.'
'If I should ever find myself in need of Inspector Lestrade,' Holmes muttered after he had gone, 'then things will have come to a pretty pass. But let us step into the alleyway, Watson. My case is complete and yet there is still one small point which must be addressed.'
"then things will have come to a pretty pass" の個所ですが、知らない単語はないのにさっぱり意味が分かりません。私の英語の先生（辞書）に相談します。
"pass" の項に次の説明がありました。
・Oxford English Dictionary: A state or situation of a specified, usually undesirable, nature.: If this was what was being taught these days in colleges things had come to a pretty pass.
・Collins Dictionary: a state of affairs or condition, esp a bad or difficult one (esp in the phrase a pretty pass)

・Cambridge English Dictionary: a difficult or unpleasant condition: If I'd been aware things had reached such a pass, I'd have told the police.
"pass" にこんな意味があるのですね。 "come to a pretty pass" が慣用句のようなので "come to a pretty pass" で調べると、英国で使われる表現のようです。

seascape

Anthony Horowitz の "The House of Silk" からの引用です。
'It's an excellent price,' he was saying. 'And I am certain of it, Tobias. These works are like good wine. Their value can only rise.'
'No, no, no!' replied the other voice in a high-pitched whine. 'He calls them seascapes. Well, I can see the sea...but precious little else. ...'
絵画の話なので "seascapes" は海の景色のことだと思いますが、念のために辞書で確認します。

peach on

Anthony Horowitz の "The House of Silk" からの引用です。
The money they had stolen from the train was already gone, frittered away on alcohol and gamblin g. As the sun set that evening, they were crouched around the stove, drinking gin and playing cards.

rent the air

Anthony Horowitz のシャーロック・ホームズ小説 "The House of Silk" を読み始めました。シャーロック・ホームズ小説なのに作者がコナン・ドイルでは無いのは何故と思いましたが、これはコナンドイル財団がコナン・ドイルの没後初めて公認したシャーロック・ホームズ小説だそうです。
'Inside the mail car, the security guard had heard the shots and I can only imagine the terror he must have felt as he unlocked the door if they had demanded it? We will never know. A moment later, a huge explosion rent the air and the entire wall of the carriage was blown apart.
"rent the air" の動詞、現在形は "rent" あるいは "rend" だと思うが、いずれにせよ、ここでの意味に合う動詞を知りません。辞書を見ます。
