ODIN (unclued God) in CG (coastguard)

Sorry, meant to type CODING

[factor-fiction]

To overhear = to catch something
Finished = OVER
Put unclued god RHEA in it
=OVERHEARD

[shaneystar2]

thebes ..t's are crossed
over hear ( finished ..over ) catch ( hear)
Coding ..Odin is the God

[factor-fiction]

Thebes is right

[cg51]

objects = these containing be

finished = over catch = hear (if you catch what was said)

[factor-fiction]

THESE containing BE doesn't work though- one E too many.
I thought the objects maybe be thes (plural of the) with BE in to give Thebes.
But I think it was simply Ts (objects to be crossed) + Hebe (unclued God)

Thank you all. I'll go with the suggestions received.
