_Julia._ Tell your echo this, Or flatterers, that like echoes still report What they hear though most imperfect, and not me; For if that you be true unto yourself, I'll know. _Card._ Will you rack me? _Julia._ No, judgment shall Draw it from you: it is an equal fault, To tell one's secrets unto all or none. _Card._ The first argues folly. _Julia._ But the last tyranny. _Card._ Very well: why, imagine I have committed Some secret deed which I desire the world May never hear of. _Julia._ Therefore may not I know it? You have concealed for me as great a sin As adultery. Sir, never was occasion For perfect trial of my constancy Till now: sir, I beseech you-- _Card._ You'll repent it. _Julia._ Never. _Card._ It hurries thee to ruin: I'll not tell thee. Be well advised, and think what danger 'tis To receive a prince's secrets: they that do, Had need have their breasts hooped with adamant To contain them. I pray thee, yet be satisfied; Examine thine own frailty; 'tis more easy To tie knots than unloose them: 'tis a secret That, like a lingering poison, may chance lie Spread in thy veins, and kill thee seven year hence. _Julia._ Now you dally with me. _Card._ No more; thou shalt know it. By my appointment the great Duchess of Malfi And two of her young children, four nights since, Were strangled. _Julia._ O Heaven! sir, what have you done! _Card._ How now? how settles this? think you your bosom Will be a grave dark and obscure enough For such a secret? _Julia._ You have undone yourself, sir. _Card._ Why? _Julia._ It lies not in me to conceal it. _Card._ No? Come, I will swear you to't upon this book. _Julia._ Most religiously. _Card_. Kiss it. [_She kisses the book._ Now you shall never utter it; thy curiosity Hath undone thee: thou'rt poisoned with that book; Because I knew thou couldst not keep my counsel, I have bound thee to't by death. _Re-enter_ BOSOLA. _Bos._ For pity-sake, hold! _Card._ Ha, Bosola! _Julia._ I forgive you This equal piece of justice you have done; For I betrayed your counsel to that fellow: He overheard it; that was the cause I said It lay not in me to conceal it. _Bos._ O foolish woman, Couldst not thou have poisoned him? _Julia._ 'Tis weakness, Too much to think what should have been done. I go, I know not whither. [_Dies._ _Card._ Wherefore com'st thou hither? _Bos._ That I might find a great man like yourself, Not out of his wits as the Lord Ferdinand, To remember my service. _Card._ I'll have thee hewed in pieces. _Bos._ Make not yourself such a promise of that life Which is not yours to dispose of. _Card._ Who placed thee here? _Bos._ Her lust, as she intended. _Card._ Very well: Now you know me for your fellow-murderer.
