The Tin Man

John Bartlett, Paul, Richard, and Jake were old friends and ex-Army mates. They had all ended up in the Special Forces Commando unit and worked in Afghanistan. Over the years they had lost contact with John Siddle, their superior officer. He had gone on to become a success in banking. The other four maintained their close friendship.
John Siddle called unexpectedly to ask John Bartlett if they could meet for lunch. At that event, Siddle disclosed something horrific to Bartlett and asked him if he could do something about it.
This throws the team of friends into a moral dilemma; they know they owe their ex-commander a great deal.
The tale takes an unusual turn with a bombshell ending that could never be foreseen by the four Special Forces friends.
