Is there an English word or phrase which describes conversations intended to be overheard by others, which primarily contains misinformation meant to be believed by those who overhear?
During an office conversation between Tim and Carlos, Tim says out loud, "Jeff will go to Singapore after leaving Hong Kong".
- It's subsequently discovered that Tim knew Jeff was not going to Singapore
- Assume that Tim merely wanted those who overheard to think Jeff was going to Singapore
"Deception" is possible, but seems too generic. I'm more interested in specifically describing the indirect nature of the event (i.e. Tim does not say this directly to those he wants to deceive).
