Aa!Siz burada mısınız?Ben de" Beklemeyip gittiler herhalde" diye düşünmüştüm

Dolaylı anlatım

Aa siz burada mısınız?Ben de beklemeyip gittiğinizi herhalde  düşünmüştüm

doğru mu acaba?

lütfen bana yardım edebilir misiniz?

I didn"t really understand what´s to be done: translate or indicate which option is the good one?

For translation, it could go (as far as I can understand as learner):

Ah! are you here? "They probably didn´t wait and went" I thought.

doğru mu acaba? ==> is it correct, may be?
lütfen bana yardım edebilir misinz? ==> Please, can you help me (give me help)?

The "Dolaylı anlatım", I think should write ´anladım´, but I couldn´t understand the word ´Dolaylı´

More explanations would also be of great help to me, thanks in advance to anyone.

No it doesn´t sounds correct. This is hard to explain but I´ll try:

In the first sentence the quotation defines the sub-clause boundaries so there is no problem. However in the second one; that "herhalde" which comes after the verb of the subclause "gittiğinizi", causes an ambiugity in the meaning. This probably has to do with the rule that Turkish sentences generally end with the verb, so that "gittiğinizi" is perceived as the end of the subclause. That "herhalde" is hanging in the air there, as if you tried to say "I probably thought you were gone" but that doesn´t sounds correct either ("Ben de beklemeyip gittiğinizi düşünmüştüm herhalde" would be correct in this case)

Anyway; just put that herhalde somewhere before the verb in the subclause. Like "Ben de herhalde beklemeyip gittiğinizi düşünmüştüm". Note that I am not sure if there is a general rule about this or anything., please correct me if I am wrong.

Remove "herhalde" from the example for dolaylı anlatım and it will be ok
