We may, then, get a light on what his task is to be.
Firstly .-- We must differentiate between what he did in London as part of his general plan of action, when he was pressed for moments and had to arrange as best he could.
Secondly .-- We must see, as well as we can surmise it from the facts we know of, what he has done here.
As to the first, he evidently intended to arrive at Galatz, and sent invoice to Varna to deceive us lest we should ascertain his means of exit from England.

His immediate and sole purpose then was to escape.

The proof of this, is the letter of instructions sent to Immanuel Hildesheim to clear and take away the box before sunrise.

There is also the instruction to Petrof Skinsky.

These we must only guess at, but there must have been some letter or message, since Skinsky came to Hildesheim.
That, so far, his plans were successful we know.
