Input: Brooke:  Gruesome murders , chills and thrills , it 's what author Richard Castle is known for , and he 's delivered yet again with two new books : " Wild Storm " and " Raging Heat " . Thank you for joining us this morning .
Richard Castle: My pleasure .
Brooke: But perhaps the bigger mystery is the _ one _ that surrounds you . Your disappearance made national headlines . Months later , you were found in a dinghy at sea , yet you claim to have no memory of where you 've been or how you got there .
Richard Castle: Yeah , I know . It , uh ... it sounds crazy , even to me , and uh , we 're still looking for answers .
Brooke: Well , your critics seem to have some . It 's no secret your last book , " Wild Storms " , slipped off the best - seller list . Is n't the most logical explanation that this is all a publicity stunt , a way to make headlines to drum up book sales ?
Richard Castle: I assure you , Brooke , it was no publicity stunt . I would never do that to my family or my fiancée .
Brooke: Speaking of your fiancée , you vanished just moments before your wedding . What do you say to fans who chalk your disappearance up to cold feet ?
Richard Castle: Well , I would say that they do n't know what they 're talking about .
Brooke: So the wedding 's still on ?
Richard Castle: Well , we ... we 've been through a very tough experience . We 're still trying to make sense of everything , actually . And I actually just ... I - I ... I came here to talk about my books .
Brooke: And if this were one of your books , Mr. Castle , would n't you find the plot a little hard to swallow ? I mean , amnesia ? Really ?
Richard Castle: Well , this is n't a novel , Brooke . This actually happened . And no one wants the truth more than I do . And I can prove it .
Richard Castle: I
Richard Castle: 'm offering a reward - $ 250000 - to anyone who can give me verifiable proof as to where I was and exactly what I was doing during the two months I was missing .
