Puzzle time: The last puzzle given by my brother in law – I am still trying to decipher the answer from three of my friends – one of whom is the brainy-types and has changed his mind thrice….

But today is Thursday and I should be flying home…. so here is one that is easier …

If you have cracked it, send me PM. I will recognize you publicly…
