Louis Mazzini: [after murdering his cousin along with his cousin's mistress] I was sorry about the girl, but found some relief in the reflection that she had presumably during the weekend already undergone a fate worse than death.

Louis Mazzini: [to the Duke, before he executes him] From here, I think, the wound will be consistent with the story I shall tell.

Louis Mazzini: How happy could I be with either, were t'other dear charmer away.

Louis Mazzini: I considered it both seemly and touching that my dear wife should visit me as she did this morning, to make her farewells. Your arrival on the other hand, appears to me unseemly and tasteless in the extreme.
Sibella: I couldn't bear my last sight of you to be that look of hatred you gave me as you went out from the trial
Louis Mazzini: In view of the fact that your evidence had put the rope around my neck, you could hardly expect a glance of warm affection.

Louis Mazzini: I couldn't help feeling that even Sibella's capacity for lying was going to be taxed to the utmost. Time had brought me revenge on Lionel, and as the Italian proverb says, revenge is a dish which people of taste prefer to eat cold.

Louis Mazzini: I had not forgotten or forgiven the boredom of the sermon of young Henry's funeral, and I decided to promote the Reverend Lord Henry D'Ascoyne to next place on the list
[to be murdered]

Louis Mazzini: I made an oath that I would revenge the wrongs her family had done her. It was no more than a piece of youthful bravado, but it was one of those acorns from which great oaks are destined to grow. Even then I went so far as to examine the family tree and prune it to just the living members. But what could I do to hurt them? What could I take from them, except, perhaps, their lives.

Louis Mazzini: I want to talk to you for a minute. If you make a noise, I shall blow your head off at once. By the time anyone has heard the shot I shall be running back toward the castle shouting for help. I shall say that you stepped on the trap and your gun went off as you fell. So be quiet.

Louis Mazzini: When I've finished I shall kill you. You will the the sixth D'Ascoyne that I've killed. You want to know why? In return for what the D'Acoyne's did to my mother. Because she married for love instead of for rank or money or land. They condemed her to a life of poverty and slavery, in a world for which they had not equipped her to deal. You yourself refused to grant her dying wish, which was to be buried here, at Chalfont. When I saw her poor little coffin saw underground, saw her exiled in death as she had been in life, I swore to have revenge on your intolerable pride. That revenge I am just about to complete.

Louis Mazzini: It is so difficult to make a neat job of killing people with whom one is not on friendly terms.

Louis Mazzini: It is so difficult to make a neat trump of killing people with whom one is not on friendly terms.
