The Unovan Government have evicted the population of this desert town so it may be used to test the effects of nuclear weaponry. The tower has been constructed and the bomb placed.

You are the detonation commander.

Because of the way the nuclear material used in this bomb works and for various other reasons, the bomb must be detonated at exactly 2pm to the second. If the detonation is delayed for any reason, the whole thing will have to be scrubbed and the nuclear material will be wasted. This will not look good on your resume and will substantially reduce the size of your pay-check.

15 seconds before detonation, you spot this little girl on one of the monitors. The eviction crews apparently missed her and she is now in the village realizing she is about to be fried. You are the only one who has noticed her. If the detonation goes ahead with her there, she has no possible chance of surviving the blast and will almost certainly be ensured a relatively unpleasant and graphic death, however her remains will also be obliterated and no-one except for you will know she was there.

What do?
