Secretive...suspicious...stealthy...

We have a small pleasure marina in front of our apartment, sailing boats, motor cruisers, friendly bars,a chatty crowd....when suddenly this black apparition glides in from the Malacca Strait, known home of pirates and smugglers....a dark mysterious crew...powerful, silenced engines it noses into the furthermost landing stage...a civilian readies himself to step off and sidle away...then it departs as stealthily as it slid in....what to make of it all???

Me reading too many thrillers as I sit on the terrace I suspect....
