Question regarding a sentence from the book I read

Hello everyone, I posted the same one earlier on different website and received correction. However I didn't get the answer for my question.

I understand that's largely because I didn't ask clear quetion.

so I am posting the correction I received

Here we go :)

I came across a sentence while reading the book, "Mastermind- How to think like Sherlock Holmes" by Maria Konnikova.

The sentence as followed:
"But that, warss Holmes, is a dangerous policy."

In the previous paragraph to this sentence, it talks about two people who were in the same situation, but their recollections about the experience could be completely different.

Each person would be certain as much as the other tha they were 100% correct.

My question is in the phrase, "warns Holmes" -- Is Holmes a subject or object?

To me it sounds like Holmes warns people but I'm not 100% sure.


I want to thank T for correcting my entry.

In the sentence ""But that, warns Holmes, is a dangerous policy,"  Holmes is the subject of the verb "warns."  

The sentence could be rewritten: "But Holmes warns that that (= the policy preciously discussed) is a dangerous policy.

A question regarding a sentence from the book I read from a book.

Hello everyone. I posted the same one question earlier on different website and received a correction. However I didn't get the answer for it my question.

I understand that's largely because I didn't ask clear question clearly.  So I am posting the correction I received.

I came across a sentence while reading the book, "Mastermind - How to think like Sherlock Holmes" by Maria Konnikova.

The sentence was,  followed:
"But that, warns Holmes, is a dangerous policy."

In the previous prior paragraph to this sentence, it talked was about two people who were in the same situation, but their recollections about the experience could be were completely different.

Each person would be was certain as much as the other that they were 100% correct.

My question is in the phrase, "warns Holmes" -- Is Holmes a subject or object?

To me it sounds like Holmes was doing the warning people but I'm not 100% sure.

I want to thank you  for correcting my entry.

Yes, Holmes is doing the warning.  

The subject of the sentence, "But that, warns Holmes, is a dangerous policy", 

if I'm not mistaken, is "that".  

"warns Holmes" is a clause and can be left out.  The sentence then becomes,

"But that is a dangerous policy".  

"But" is just an emphasis and the sentence is further reduced to,

"That is a dangerous policy".  

Now you can see from this simplified that "That" (whatever it is denoting) is the subject of the sentence.  "policy" is the object.

Holmes is the one speaking, the one who is warning others. 

It could also be written as:

"But that," Holmes warns, "is a dangerous policy." It has the same meaning (but some people might say it doesn't sound quite as good or poetic) and perhaps it makes it more clear that Holmes is the one speaking?
