Secrets of this description are death to those with whom they are deposited. Burn it, and you will have saved John and Cornelius de Witt.
"Farewell, and love me.
"Cornelius de Witt "August 20th, 1672."

Five minutes had not elapsed, before a long and shrill whistle was heard through the din and noise of the square of the Buytenhof.
John gratefully raised his eyes to heaven.
"And now," said he, "let us off, Cornelius."
