Last Window: Step-by-step walkthrough

Defogging the Last Window

Last Window: Step-by-step walkthrough

The last time we saw Kyle Hyde, he was flogging his wares in Hotel Dusk, trying to piece together the mystery surrounding his ex-partner and the murder of his father some 25 years past.

A stylish blend of film noir and interactive novel, Last Window: The Secret of Cape West is the second outing for the ex-cop turned salesman, and picks up shortly after the events of Hotel Dusk, with Kyle still on the trail of his deceased dad.

Although the majority of puzzles in Last Window are finely balanced, some of the later tasks require all the wit and guile of a master detective. In fact, unless you happen to reside at 221B Baker Street, it's quite likely you've already found yourself stumped.

And so, for the benefit of those of you who weren't penned by Sir Arthur Conan Doyle, here's our step-by-step solution to every last one of those dastardly puzzles.
