Retrieve record Many to Many relationship

Hello Expert,

I have a requirement, there is many to many relationship between entities. I need to fetch record(just count is enough).

My scenario is below:

I have four entities A,B,C,D and my requirement is to retrieve D from A entity but there is no direct relationship.

A and B has N:N relationship and

B and C has N:N relationship and

C and D has 1:N relationship (C is Parent and D is Child).

Kindly suggest the possible ways.

I am trying to use multiple "LinkEntity"  and "RetrieveMultiple"

Could you please help me do this in better way.

Thanks in Advance.
