Fraudulently devised building project? (3-2,3)
I believe the answer is:
put-up job
'fraudulently devised' is the definition.
I know nothing about this answer so I can't judge whether this works.
'project?' is the wordplay.
I cannot quite see how this works, but
'project?' could be 'job' (project is a kind of job) and 'job' is found in the answer.
The remaining letters 'putup' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'building' is the link.
Can you help me to learn more?
(Other definitions for put-up job that I've seen before include "Dishonest scheme" , "Deception arranged in advance" , "Something intended to deceive" , "Prearranged underhand deceitful enterprise" , "sham!" .)
