Is there a hidden story within Matthew's Gospel?

Could this Gospel contain clues about the death of Jacob (known to followers of Jesus as "the Lord's brother") in Jerusalem in 62 C.E.? Revered as "the Righteous," Jacob was publicly executed within the temple precincts; yet why did he die at this particular Passover? Through a careful study of key passages, this book uncovers evidence that Matthew's Gospel preserves the background to this little-known story.
