Character History[]
Theo was an archaeologist and along with Claudio discovered Another Page, the missing page of "The Travels of Marco Polo" at the prison cell where Marco Polo was locked up.
The chain of events differ between Lupin III and Claudio, the latter account being unreliable. Lupin saw that Claudio blames Bernardo Vilar for the murder. Claudio believes that after Theo wanted to destroy the manuscript due to that it would cause wars, he found out about the legacy and Theo was strangling him due to that he looked into his secret diary. After looking at Bernardo, Claudio looks at Theo who vows to protect Another Page and threw a grenade.
He was murdered by Claudio with the manuscript, first with a wack on the ear causing blood to drop and finally on the head. Lupin gave him his condolences and took his diary however he was framed for the murder as the police found him at the scene of the crime.
The only relation left in the family is his granddaughter Lisa Argento.
