Proof
Wine merchant Tony Beach has expertly catered his latest society soiree, but the fun`s over when a team of hit men crashes the party...literally. The event leaves Tony with a bitter aftertaste of suspicion--and sets off a mystery that`s an intoxicating blend of deception, intrigue, and murder...

   fr. probare to prove. See {Prove}.]
   1. Any effort, process, or operation designed to establish or
      discover a fact or truth; an act of testing; a test; a
      trial.
            For whatsoever mother wit or art Could work, he put
            in proof.                             --Spenser.
            You shall have many proofs to show your skill.
                                                  --Ford.
            Formerly, a very rude mode of ascertaining the
            strength of spirits was practiced, called the proof.
                                                  --Ure.
   2. That degree of evidence which convinces the mind of any
      truth or fact, and produces belief; a test by facts or
      arguments that induce, or tend to induce, certainty of the
      judgment; conclusive evidence; demonstration.
            I'll have some proof.                 --Shak.
            It is no proof of a man's understanding to be able
            to confirm whatever he pleases.       --Emerson.
   Note: Properly speaking, proof is the effect or result of
         evidence, evidence is the medium of proof. Cf.
         {Demonstration}, 1.
   3. The quality or state of having been proved or tried;
      firmness or hardness that resists impression, or does not
      yield to force; impenetrability of physical bodies.
   4. Firmness of mind; stability not to be shaken.
   5. (Print.) A trial impression, as from type, taken for
      correction or examination; -- called also {proof sheet}.
   6. (Math.) A process for testing the accuracy of an operation
      performed. Cf. {Prove}, v. t., 5.
   7. Armor of excellent or tried quality, and deemed
      impenetrable; properly, armor of proof. [Obs.] --Shak.
   {Artist's proof}, a very early proof impression of an
      engraving, or the like; -- often distinguished by the
      artist's signature.
   {Proof reader}, one who reads, and marks correction in,
      proofs. See def. 5, above.
   Syn: Testimony; evidence; reason; argument; trial;
        demonstration. See {Testimony}.
   

2. \Proof\, a.
   1. Used in proving or testing; as, a proof load, or proof
      charge.
   2. Firm or successful in resisting; as, proof against harm;
      waterproof; bombproof.
            I . . . have found thee Proof against all
            temptation.                           --Milton.
            This was a good, stout proof article of faith.
                                                  --Burke.
   3. Being of a certain standard as to strength; -- said of
      alcoholic liquors.
   {Proof charge} (Firearms), a charge of powder and ball,
      greater than the service charge, fired in an arm, as a gun
      or cannon, to test its strength.
   {Proof impression}. See under {Impression}.
   {Proof load} (Engin.), the greatest load than can be applied
      to a piece, as a beam, column, etc., without straining the
      piece beyond the elastic limit.
   {Proof sheet}. See {Proof}, n., 5.
   {Proof spirit} (Chem.), a strong distilled liquor, or mixture
      of alcohol and water, containing not less than a standard
      amount of alcohol. In the United States ``proof spirit is
      defined by law to be that mixture of alcohol and water
      which contains one half of its volume of alcohol, the
      alcohol when at a temperature of 60[deg] Fahrenheit being
      of specific gravity 0.7939 referred to water at its
      maximum density as unity. Proof spirit has at 60[deg]
      Fahrenheit a specific gravity of 0.93353, 100 parts by
      volume of the same consisting of 50 parts of absolute
      alcohol and 53.71 parts of water,'' the apparent excess of
      water being due to contraction of the liquids on mixture.
      In England proof spirit is defined by Act 58, George III.,
      to be such as shall at a temperature of 51[deg] Fahrenheit
      weigh exactly the 12/13 part of an equal measure of
      distilled water. This contains 49.3 per cent by weight, or
      57.09 by volume, of alcohol. Stronger spirits, as those of
      about 60, 70, and 80 per cent of alcohol, are sometimes
      called second, third, and fourth proof spirits
      respectively.
   {Proof staff}, a straight-edge used by millers to test the
      flatness of a stone.
   {Proof stick} (Sugar Manuf.), a rod in the side of a vacuum
      pan, for testing the consistency of the sirup.
   {Proof text}, a passage of Scripture used to prove a
      doctrine.
   

1. A finite sequence of well-formed formulas, F1, F2, ... Fn, where each Fi either is an axiom, or follows by some rule of inference from some of the previous F's, and Fn is the statement being proved.
