translation - Nuance when the subject is moved to the end of the phrase

I've been plugging away on novel translations for years now and figure I should ask more questions about it around here, since the freelance life does not make it easy to network with people.

My question today regards when the subject of the sentence is moved to the end of a phrase. Take the following sentence (taken from the novel I'm currently working through):

ロンドン市内{しない}で『騎士派{きしは}』の連中{れんちゅう}を踏{ふ}み潰{つぶ}すべくゴーレム＝エリスを放{はな}ったシェリーだったが、どこかで意識{いしき}が途絶{とだ}えていた。

Obviously, the subject of this sentence is シェリー (Sherry), as it is her doing the action in the first phrase, and the second phrase is regarding her. However, instead of writing it in a more standard way:

シェリーはロンドン市内で『騎士派』の連中を踏み潰すべくゴーレム＝エリスを放ったが、どこかで意識が途絶えていた。

the author opts to place シェリー at the end of the phrase. My question is, what sort of nuance does this have? For example, I'm familiar with this type of inversion of action and subject:

ロンドン市内で『騎士派』の連中を踏み潰すべくゴーレム＝エリスを放ったのはシェリーだったが、どこかで意識が途絶えていた。

In that case, the emphasis is on who exactly was the one who did the action, as though it was a question the author is answering. This works much the same as the equivalent grammatical structure in English.

However, I'm not sure if what the author wrote is different from that, and if it is, how it's different. My gut instinct is to translate this in the same way as the のは construction:

Sherry had been the one to...

It was Sherry who had...

But I'm not honestly sure this would properly communicate the nuance involved. Obviously it would depend on context. What I'm getting from the sentence is that she knew that logically she had performed this action, but she wasn't conscious for the whole thing.

This author tends to use this construction very frequently, much more frequently than other authors I've read. (In fact, I counted about 10 instances of it for just the protagonist's name in this one book.)　I also frequently see it simply to end a sentence, such as in:

ほとんど窒息{ちっそく}しそうになり、生命{いのち}の危機{きき}を回避{かいひ}するために仕方{しかた}なく咀嚼{そしゃく}を始{はじ}めるシェリー。

I believe this is the same construction. What's the nuance here?

Answer

1. シェリーはゴーレムを放ったが、…


2. ゴーレムを放ったのはシェリーだが、…


3. ゴーレムを放ったシェリーだが、…

Sentence 2 is a plain old cleft sentence, I think you understand it well.

Sentence 3 is a "体言止め-like" expression which is basically more vivid and dramatic than 1. Grammatically speaking, it's just a long relative clause that modifies シェリー. By definition, 体言止め refers only to ending a whole sentence with a noun, but a similar construction happens before だが/が/けど/etc. This is a very common rhetorical device in Japanese. Lyrics of some songs are written almost exclusively with 体言止め (for example, this).

The difference between 2 and 3 is small, but some "contrasted" clause about シェリー tends to follow after Sentence 2 because it has は. (e.g., "ゴーレムを放ったのはシェリーだが、そのシェリーがゴーレムに殺されたのだ。")

To translate 体言止め, I think you can treat it as an ordinary sentence in many cases, especially when an author/lyricist tends to use it everywhere. You can use "Sherry, the one who unleashed..." or "It was Sherry who have unleashed..." when appropriate, but IMHO that can often result in awkward English sentences. For example, the first part of 残酷な天使のテーゼ is often translated like this:

蒼い風がいま　胸のドアを叩いても
私だけをただ見つめて微笑んでるあなた
A blue wind is now knocking at the door to your heart, yet

You are merely gazing and smiling at me

(The literal translation is "You, the one who is gazing and smiling at me even if a blue wind is...")
