"That was (это был), of course (конечно), the obvious line to take (очевидный путь, /чтобы его/ придерживаться). But why me (но почему я)? Why Hercule Poirot? Greater publicity could be ensured by sending the letters to Scotland Yard (если отправить письма в Скотланд-Ярд, можно было бы добиться большей известности: «б'oльшая известность могла быть обеспечена отправлением писем в Скотланд-Ярд»). More again by sending them to a newspaper (еще б'oльшая, если отправить их в газету). A newspaper might not print the first letter (газета, вероятно, не напечатала бы первое письмо), but by the time the second crime took place (но к тому моменту, когда произошло второе преступление), A.B.C. could have been assured of all the publicity (Эй-би-си мог бы быть уверен во всей известности) the press could give (которую пресса могла дать). Why, then, Hercule Poirot? Was it for some personal reason (было это по какой-то личной причине)? There was (было), discernible in the letter (заметное в письме), a slight anti-foreign bias (легкое предубеждение против иностранцев; bias — наклон; предубеждение) — but not enough to explain the matter to my satisfaction (но недостаточное, чтобы объяснить дело, /чтобы/ я был удовлетворен: «до моего удовлетворения» = удовлетворительно в моих глазах)."

"Then the second letter arrived (затем прибыло второе письмо) — and was followed by the murder of Betty Barnard at Bexhill (и /за ним/ последовало убийство Бетти Барнард в Бексхилле). It became clear now (тут стало ясным) (what I had already suspected (что я уже подозревал)) that the murders were to proceed in an alphabetical plan (что убийства должны были следовать в алфавитном порядке), but that fact (но тот факт), which seemed final to most people (который казался окончательным для большинства людей), left the main question unaltered (оставлял главный вопрос неизменным; to alter — изменять) to my mind (для моего ума). Why did A.B.C. need to commit these murders (зачем Эй-би-си было необходимо совершать эти преступления)?"

Megan Barnard stirred in her chair (Меган Барнард заерзала на своем стуле; to stir — шевелиться; двигаться). "Isn't there such a thing as (нет ли такой вещи как) — as a blood lust?" she said (как жажда крови?).
