Let's solve the expression step by step:

$-7 + 4 - (-5) + (-1)$

1. Start by simplifying the double negative $-(-5)$, which becomes $+5$:

$-7 + 4 + 5 + (-1)$

2. Now, combine the terms from left to right:

$-7 + 4 = -3$ $-3 + 5 = 2$ $2 + (-1) = 1$

So, the value of the expression is:

$\boxed{1}$
