Once again a client thanked me this week for providing closure.  I was able to uncover information which solved a 58 year old family mystery.  Looking back over thirty-plus years of investigating I realize closure is what private investigators deliver.  We produce finality.  We clear the way for our clients to have a more realistic understanding of the situation.  This new understanding gives the client a newfound sense of peace.  The client can now re-invest their emotional energies elsewhere.
