Thank you for using the Jiskha Homework Help Forum. The direct object will be answered by the question "what." Since "what" Jack told is not stated, therre is not direct object there. If you can add the word (to, at, from, of) and restate "to WHOM did Jack tell... that will identify the indirect object. So, in "Jack told me" "me" is the indirect object pronoun. However, in "Jack told the secret to me" "the secret" is the direct object!
