MR DUBE
First of all as I've noted, my work was very clandestine, and another thing is I was supposed to be always vigilant and secured.  I would have to be very alert in case I fall into the enemy's hands.  When I walk around or drive around I will not have my eyes closed, I would have to be very alert.  This kept happening, quite often, and he knew my position and the nature under which I was working, so those things brought questions to me and hence I was suspicious.
