Join to table specified as string in column and no foreign key

Last Modified: 2012-06-27
I have inherited a db which sets out a series of modules to which users may or may not have certain permissions to do things (add, edit, delete) .  These permissions are defined in other tables (called Permission1, Permission2, Permission3) and the names of the tables in which the permissions defined are set out in a column of the modules table.  

My challenge is to create a query so that all the Modules are shown and any permissions to these modules.  The attached spreadsheet shows the simple tables and type of result that I am trying to achieve.

Any help in doing this would be greatly appreciated

The tables are as follows:
ModuleId	Module	RelatedTable		
1	Alpha	"Permission1"		
2	Beta			
3	Charlie 	"Permission2"		
4	Delta	"Permission2"		
5	Foxtrot	"Permission3"		
Permission1 Table				
UserId	View	Edit	Delete	
1	yes	no	no	
2	no	yes	no	
3	yes	no	no	
UserId	View	Edit	Delete	
3	yes	no	no	
1	no	yes	no	
UserId	View	Edit	Delete	
3	yes	no	no	
4	no	yes	no	
5	yes	no	no	
Results of Query to Get Module Permissions where User = 1				
ModuleId	Module	View	Edit 	Delete
1	Alpha	yes	no	no
2	Beta	no	yes	no
3	Charlie 	null	null	null
4	Delta	null	null	null
5	Foxtrot	null	null	null
