Why Narcissa Malfoy?

In DH, out of all the DEs around, LV chose Narcissa Malfoy to check if Harry is still alive. 

Bellatrix is his trustworthy lieutenant and cannot-be-lost-to-Potter-just-in-case-he-is-alive material, I suppose. Alright. Maybe he felt somewhat similar about the rest of the DEs too. 

But why not say Lucius? Lucius has at least been trying hard to get back to LV's good books. Narcissa has been giving a deadpan stare for quite a long time. True that she was excited to see the Trio at Malfoy Manor but she was not as excited as her husband and was not there (at least Harry didn't see her in his vision) in the "running race" to escape LV's fury that followed the event. And I don't think her disappointment in Draco's treatment would have been missed by LV. 

So, why do you think he chose Narcissa Malfoy of all the people?
