` Sir , is not General Arnold here ? ' asked Washington in surprise . '' ` No , sir , ' replied Colonel Lamb , ` he has not been here these two days , nor have I heard from him within that time . ' `` That aroused Washington 's suspicions , but he went around examining the works at West Point , and about noon returned to the Beverly Dock , from which he had departed . `` As he was going up from the river to the house , Hamilton was seen coming toward the party with a hurried step and an anxious , troubled countenance . He said something to Washington in a low tone ; they went into the house together , and Hamilton laid before the chief several papers which furnished conclusive evidence of Arnold 's guilt . They were the documents which Arnold had put in André 's hands .
