had come up with a single defence tactic: to ask for a new examination of the mental state of his client. The doctor he had chosen had told the court:
âDiminished responsibility â¦â
To which the reply from the prosecution was:
âThis was a cold, callous and appalling crime! If Heurtin didnât steal anything, it was because he was prevented from doing so by some circumstance or other. All told, he struck his victims eighteen times with a knife!â
Photographs of the victims had been handed round the members of the jury, who pushed them away with disgust.
âGUILTYâ, on all counts.
Death! The next day, Joseph Heurtin was transferred to the top-security block with four other men who had also been sentenced to death.
âIsnât there anything you want to tell me?â Maigret made a point of coming to ask him, for he was not happy with himself.
âNo.â
âYou do know youâre going to be executed?â
Heurtin wept, still as pale as ever, his eyes red.
âWho was in this with you?â
âNobody.â
Maigret returned every day, even though officially he had no business looking into the case any further.
And every morning he found Heurtin more and more crushed but calm. He had stopped shaking. There was even, at times, a glint of irony in his eyes â¦
 â¦Â until the morning the prisoner heard footsteps in the next cell, and then loud screams.
They had come to fetch number 9, a son who had killed his father, to take him to the scaffold.
The next day, Heurtin, number 11, was in tears. But he said nothing. All he did was lie stretched out on his bunk with his teeth clenched and his face to the wall.
When Maigret got an idea into his head, it stayed anchored there for a long time.
He went to see Coméliau and told him: âThat man is either mad or heâs innocent.â
âImpossible! In any case, sentence has been passed on him.â
Maigret, 1 metre 80 tall, powerful and as burly as a market porter, dug his heels in.
âDonât forget that the prosecution was unable to establish how he got back to Paris from Saint-Cloud. He didnât take the train. He didnât get on a tram. He didnât walk back!â
Jokes were made at his expense.
âWould you like to try an experiment?â
âYouâll have to take this to the minister!â
And Maigret, solemn and stubborn, did so. He himself wrote the note which gave Heurtin the escape plan.
âListen! Either there were others in it with him, and heâll think the note is from them, or there werenât, in which case heâll be on his guard and suspect a trap. Iâll take full responsibility for him. You have my
absolute word that he wonât escape.â
The inspectorâs stolid, calm, rock-hard face was a sight to be seen!
The tussle lasted three days. He raised the spectre of a miscarriage of justice and the scandal which would follow sooner or later.
âBut youâre the one who arrested him!â
âBecause, as a policeman, itâs my job to draw logical conclusions from the material evidence presented.â
âAnd as a man?â
âIâm still waiting to be morally sure â¦â
âAnd?â
âEither heâs mad or heâs innocent.â
âWhy doesnât he say anything?â
âThe test I propose will tell us why.â
Then there were phone calls, discussions â¦
âYouâre putting your career on the line, detective chief inspector. Think about it!â
âI have thought about it.â
The note was duly passed to the prisoner, who had not shown it to anyone and, for the last few days, had eaten with a heartier appetite.
âSo he wasnât surprised!â said Maigret. âTherefore he was expecting something of the sort! Therefore he has accomplices who may have promised theyâd get him out.â
âUnless heâs
