It seems to me McCluskey was not on the Corleones payroll? and from what we saw in the movie – McCluskey “setting Vito up for Sollozzo to finish him off” - sort of makes sense now....

It is fleshed out in the book McCluskey was peeved he has to return the money because Sollozzo's men couldn't get to Vito
He was also under the impression Michael would surrender after killing Sollozzo It never occurred to him he was his next victim
