Here's the sentence :

> さてと・・・それじゃあ捜査を始めるとしようか。

I would have understood if the sentence was : "さてと・・・それじゃあ捜査を始めよう", but I
don't understand the rest of the sentence. Is "としよう" some kind of grammar ?

As for the context, the characters were just about to investigate a murder.

question
grammar
さてと・・・それじゃあ捜査を始めるとしようか。
捜査を始めよう means "Let's start the investigation", but 捜査を始めるとしようか means something
more along the lines of "should we try and start the investigation",
basically. It's along the lines of ～ようとする・～ようにする

食べようとする I'm about to eat. (I'm going to try to eat) (Maybe you don't have a
lot of time or something.)(attempt to do something)

食べるようにする I will try to eat. (Try to eat something you don't like, or maybe
you're sick)(non-momentum, or continuous conscious effort)
