This is an error I have been noticing in a couple of the Michael Connelly books I have read lately. I was surprised that these errors hadn’t been picked up by the editor or corrected in newer editions. When writing, it is sometimes hard to know whether to use who or whom. When reading, however, you generally pick it up because a whom in the wrong place really destroys the rhythm of the sentence.
Reading aloud is a great tool when checking a text. It picks up long sentences, dangling modifiers, commas in the wrong places, and other syntactical errors.
- Who is the subject of a sentence (if you can replace it with he, then use who)
- Whom is the object of a sentence (if you can replace it with hiM, then use whoM)
