"On 21st April, my husband told me that he had to go out urgently on an interstate meeting. (He is a freelance cryptographer and provides consultancy to clients.) At that time, he assured me of his return in three days, but it has been more than a week, and there is no sign of him except a letter that he sent on 22nd.
Partial contents of his letter are possibly encrypted, and make no sense to me."

Dear Tamsyn,
Yesterday, I had to hastily leave out of town due to a surprise meeting, and so, was unable to describe to you the details of this trip. I am very sorry for that. Regretfully, I cannot share those details even now, as the gravity of the matters surrounding this trip have dramatically increased today.
Don't worry though, as I will surely return back before our anniversary on 26th, and we'll celebrate at the Laurel's.
Take care.
With love.
Yours forever,
Thomas Wright
P.S.

What could possibly be written in that encrypted text? His whereabouts? Some note? Just a prank? or, some Warning?!
Time to find out yourself. (Hint: Use the Caesar Tool from Cryptolab)
