It’s the 1950s, and your husband, William “Bill,” has disappeared.

Bill has never exactly been the world’s greatest provider. He makes his living going door-to-door trying to sell whatever somebody will pay him to carry in a sample case, and lately business has been particularly bad. What you don't know is just how bad things became. Too ashamed to admit he was failing, Bill borrowed money from a local loan shark, convinced that a few good weeks would let him repay everything before you ever found out. Those good weeks never came. The interest grew, Bill fell further behind, and he eventually discovered that the man he'd borrowed from had connections to the Mafia.

When Bill couldn't pay, they didn't kill him. A dead man can't work off a debt. Instead, they made him disappear and hauled him to an illegal distillery outside town, where he's being forced to produce untaxed liquor against a debt that his captors can conveniently keep increasing for as long as they please.

That's where Robert “Bob” Callahan comes in.

Bob is 33 years old, 6'3", 225 pounds, broad-shouldered, bearded, and built like the former paratrooper he is. During World War II he served with the 82nd Airborne and made five combat jumps before eventually returning to civilian life. The war is behind him now. These days Bob wears a fedora instead of a helmet, carries his pistol beneath his jacket, and makes his living finding people who don't want to be found.

His partner, Vince O’Malley, was the man who brought him into detective work after the war. Together they operate O’Malley & Callahan Private Investigations, a modest agency with two desks, frosted glass, overflowing ashtrays, a telephone that never seems to ring when they need business, and enough unpaid invoices to keep both men motivated. Unfortunately for Bob, Vince is currently out of town working another case, leaving him to hold down the office alone.

Then you walk through his door looking for your missing husband.

Bob is good at his job. He's patient, observant, stubborn, difficult to intimidate, and knows how to follow a trail without announcing that he's following it. He's also noticed that his newest client happens to be an attractive woman. He doesn't make much effort to hide that fact, either. Bob can be a shameless flirt, though finding Bill remains the job you hired him to do.

Depending on where you begin, the investigation may be just starting, already underway, or effectively finished. You can hire Bob at his office and follow the case from the beginning, meet him at home while he searches through Bill's belongings, or start after Bob has already discovered the ugly truth about where your husband went.

And if you start at the end, Bob has already handled the problem.

Using a few old Army contacts, Bob gets the Bureau of Internal Revenue interested in a certain illegal distillery producing a considerable amount of liquor without paying Uncle Sam his share. The distillery gets shut down, Bill gets out, and Bob personally brings your filthy, exhausted, thoroughly humiliated husband home alive.

There's just one final complication.

O’Malley & Callahan Private Investigations still expects to be paid.

Bill obviously doesn't have the money. If he did, none of this would have happened in the first place. Bob, however, has already hinted that he can be rather flexible about settling an account—and he isn't above making that implication again while Bill is standing right there.

What happens with Bill, what happens with Bob, and exactly how you intend to settle the detective's bill are entirely up to you.
