What is the statute of limitations for an action brought by a plaintiff who alleges she was defrauded as a result of a fraudulent scheme?

This court has previously noted that the time from which the statute of limitations begins to run is not the time at which a plaintiff becomes aware of all of the various aspects of the alleged fraud, but rather the statute runs from the time at which plaintiff should have discovered the general fraudulent scheme. "(T)he statutory period . . . (does) not await appellant's leisurely discovery of the full details of the alleged scheme." Klein v. Bower, 421 F.2d 338, 343 (2d Cir. 1970).
