A couple went on for a climbing trip.
But only the husband returned from the vacation
and said that his wife slipped off while climbing and died.
On investigating, the local sheriff arrested him saying,
“Your travel agent called. You murdered your wife.”
The man did not inform anyone about the trip.
Then how did the agent was so sure that it is a murder?
This is because the man bought only a one-way ticket for his wife whereas he bought a two-way ticket for himself.
