Snape's Task/Mission

Koinonia, I agree with you that I hadn't considered other 
possibilities than Snape's returning to spy on Voldemort.  Your idea 
of his becoming Harry as a decoy is superb.  Doreen's idea of a 
mission to the Dementors also strikes me as necessary and plausible.  
 
I maintain, however, that JKR has imbued Voldemort witht the power to 
detect all lies, perhaps in order to make situations as we are 
discussing now not to be trivial in solution.  It is documented in 
several instances in the canon:  at the end of Philosopher's Stone 
with Harry; at the beginning of Goblet of Fire with Bryce and, I 
believe, with Wormtail. What is even more compelling is that
Voldemort 
himself asserted this as his power; he didn't simply deduce that the 
others were lying.
