SQL Select WHERE row updated

Question

USE [RF_WORLD]
GO
/****** Object:  Trigger [dbo].[lastdeathtrigg]    Script Date: 08/20/2012 10:52:58 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER TRIGGER [dbo].[lastdeathtrigg]
   ON  [dbo].[tbl_pvporderview]
   AFTER UPDATE
AS 
IF (UPDATE(Death))
BEGIN
    SET NOCOUNT ON;
DECLARE @userserial int;
SELECT @userserial ='serial' WHERE UPDATE(Death)
Insert INTO [RF_WORLD].[dbo].[lastdeath]
(serial)
VALUES (@userserial)
END

The where part is suspicious, woudl it work like that? essentially i need it to only select the row serial value if it actually updated.
