I believe I have made as detailed and exhaustive a study of his personality and home life as it is possible for any being to make.

译文大概是，我认为我尽自己努力对他的性格和家庭做了最详细的调查。

然后一点点看这个句子。

I believe......

believe主导的宾语从句，省略（that）

I have made......

从句部分

made as detailed...as it is possible 和 for any being to make

这俩是特殊句式和固定搭配的用法。

总的来说，就是一个宾语从句，不过夹杂了比较复杂的短语和as...as句式。

主要信息就是下面加粗的部分。

I believe I have made as detailed and exhaustive a study of his personality and home life as it is possible for any being to make.

太久没看语法了，如有疏漏，希望不吝指正。
