"So," Lucinda says, "your explanation for events is that Laney broke his own ribs... somewhere... and was transported home, by someone other than you, even though you are the family's driver and were working that day... and even though an ambulance would have taken him directly to the hospital... and that none of these things struck you as potentially worth informing the police, so even when Officer Kerenksy sought you out specifically you only told him... 'dunno'. Is that right?"
