This walkthrough is freakin awful. It's more like a synopsis of the story. Doesn't help me solve cases at all.

The Gas Man
With your demotion comes a new partner in the form of Herschel Biggs. You'll need to check out two fires: one at the Steffens and the other at the Sawyers. For now visit the first.

At the Steffans home you'll find a heater serviced by Ryan on the left of the house and a Competition Ticket from Gulliver's Travels. Talk to Don Steffens, trusting him about the competition and doubting what Suburban Redevelopment is.
At the Sawyer home you can also find a regulator valve on the ground to the right of the house. After checking out the home you can chase down a suspect, Herbert Chapman. You can also get some more short info about the Sawyers from Joanna Alford, but you can't ask her questions.

For now head to Gulliver's Travels and check the registry for the Steffans and Sawyer's details. Next to the clerk John Cunningham. He tells the truth regarding Suburban Redevelopment, but doubt his knowledge about the promotion. With this new info head over to Suburban Redevelopment.

There isn't much to do here, but you will automatically gain a lead to Fire Station No 32, so head there now. Talk to Lynch and look at the Sawyer heater (serviced by Varley). Next line up the three pieces he gives you so the pilot light is on the far left and the gas balloon is on the right. Next go to the InstaHeat headquarters.
Once here talk to Ivan Rasic. Learn more about the valve and speak to him further. Doubt what he says about the Model 70 and point out his lies regarding his employees by mentioning Varley. Now use a phone and call R and I to cross check the employee list. You will get word to check out Clemens, Ryan, and Varley. Talk to Rasic again to get addresses.

Now check the lockers of all three workers. Both Clemens and Ryan have anarchist works among their possessions, and Varley has extra mosquito coil. Exit the headquarters and search for the suspects.
Herschel feels there isn't enough to take in Clemens; however you can doubt him about his knowledge of Varley and his employment, but you will need to use the anarchist literature to spot his lie about Ryan. For Ryan he will attempt escape by driving off in his van; same into him like all other chases to capture him. For Varley he will try to escape on foot. Aim at him with your gun to bring him to a stop.

Back at the station interview both suspects. For Ryan use the Anarchist literature to call out his first lie, use his bosses' statements to catch his second lie, doubt his knowledge of Suburban, and use his criminal record to disprove his last lie. For Varley use the heater he serviced to call out his first lie, Ryan's statement for the second lie, and the coils for the third lie.
Both look fairly guilty. Charge Ryan with the arson and send Varley back to Detroit to face his murder charge.
