I Bet 99.99% Will Fail!

A rich man that lived in a beautiful house on Baker Street, Mr. Ronald Green, has just been kidnapped and Sherlock Holmes has been appointed to the case. He finds a note at the crime scene written by Mr. Green. It read:

“First of January, Fourth of October, Fifth of March, Third of June.”

Sherlock knew that somehow, the killer’s name was hidden in the note. The suspects were as follows:

Jack Green, the son and the heir of the property
John Jacobson, an employee of Mr. Green
June Green, Green’s wife

Sherlock deduced the killer’s name in an instant. Can you?

Good luck and pass it on!
