Dulwich destroyed Met Police in this clash of the top two at Imber Court, with a four-goal first-half blitz to send them seven points clear.
Hamlet's very future may be uncertain but they made sure of the victory in Surrey with a marvellous opening 45 minutes.
Following a comprehensive 4-1 win away at Burgess Hill on Tuesday, Met Police came in to the game full of confidence.
But in the process of rushing to victory, Hamlet ended the Mets' long unbeaten run with four goals in 24 minutes, after a relatively even start.
Dulwich went ahead in the 15th minute as Reise Allassani struck the ball low and hard from outside the box into the bottom corner.
The visitors were on the front foot and doubled their lead five minutes later with Allassani rounded keeper Luke Williams and driving home his and his side's second goal , even though Will Salmon did his best to keep it out on the line.
Dulwich sensed they could kill off the game early and kept on the ascendancy.
And on 31 minutes they made it 3-0, Mark Weatherstone having the simple task of heading home from six yards giving Williams no chance.
Despite the scoreline, the Met were still presenting a threat.
Jonny Wright was winning plenty of flick-ons for Lloyd Macklin and Bayley Mummery to try and get on the end of.
But the strike duo couldn't quite marry up the ball and the run.
And Hamlet's first half scoring wasn't done, as they found a fourth goal six minutes before half-time.
Superb work on the right from Nana Boakye-Yiadom allowed him time and space to deliver a great cross for Allassani to get his header on target.
Allassani may have thought he had his hat-trick. However, he will have to fight for it, after Anthony Acheampong seemed to tap it on the line.
The home side continued to battle in the second half and did not give up the fight.
Sam Gallagher's glancing header from a corner came back off the bar and Macklin had a few shots from distance.
The Blues did get some reward in the 68th minute, as Tom Bird was fouled in the box for a clear penalty.
Macklin's effort was initially saved by Hamlet keeper Preston Edwards but Isaac Newton followed up to finish from the rebound.

The Tuesday copy of the 'South London Press' led their small non-league column with our emphatic win...

Hamlet put in an arresting display

Dulwich Hamlet are seven points clear at the top of the Bostik League Premier Division after a 4-1 win at Metropolitan Police.
It was first versus second place going into the game at Imber Court Sports Club but a Reise Allassanin double was followed by goals from Marc Weatherstone and Anthony acheampong inside the opening 39 minutes.
Zack Newton claimed a second-half consolation but Dulwich are undefeated in 11 league matches.

On Thursday the weekly 'Southwark News' headlined our report with the midweek draw at Hendon:

Late drama as Hayles bags Hamlet point

Dulwich Hamlet staged a remarkable late comeback on Tuesday night to come from two goals down in the final ten minutes to rescue a 3-3 draw at Hendon in the Bostik League Premier Division.
Rampant last weekend when they thrashed Metropolitan Police 4-1, Hamlet showed another side to their character as they resiliently refused to give in despite the cause looking lost.
Gavin Rose's side had fallen behind to Niko Muir sixth-minute goal for the hosts, before Ashley Carew levelled nine later.
But Hendon almost immediately regained the lead through Dave Diedhiou before Muir made it 3-1 just before the break to seemingly put his side in total control.
They maintained the advantage until nine minutes from time when Carew made it 3-2 from the spot.
And in the last minute of added time, with the last kick of the game, Rickie Hayles slammed in the equaliser to spark manic celebrations among the away support.
The result saw Hamlet stretch their lead at the top of the table to six points, though big spenders Billericay Town, in second, have five games in hand.
On Saturday, Reise Allassani scored a hat-trick as Hamlet romped to a win against then-second-placed Met.
The visitors scored all their goals before half-time, with Marc Weatherstone making it 3-0 before Allassani got his third six minutes before the break.
Zack Newton scored a 68th-minute consolation for the hosts.
Hamlet face Lowestoft Town in the League at Champion Hill on Saturday.

And in Friday's weekend edition of the 'South London Press' it was the previous week's hat-trick hero who took the headlines:

Allassani deal a big boost for Hamlet cause

Reise Allassani is set to sign a contract with Dulwich Hamlet by the end of this week-but manager Gavin Rose admits they will face a battle to retain his services in the January transfer window.
The former Crystal Palace attacker has dazzled for the Bostik League Premier Division leaders after his return to action following a major knee injury.
Allassani was due to sign for Sheffield Wednesday following his release by the Eagles in July 2016 before he was ruled out long term.
He has netted nine times in as many appearances for Dulwich.
"We've had about seven or eight Championship clubs and one Premier League club show an interest -plus a League Two club," said Rose. "He has scored so many goals in a short period of time. He has got a good CV. It's not rocket science that people are going to be interested in him. With what Reise has done in a short period of time, I don't see him going on trial. He is due to sign a contract in the next day or two. He has played at a high level already and proven himself-what he is doing now is showing everyone he is back fit. We'd expect him to go, of course, but we want to keep him as long as we possibly can. He has agreed to sign a contract with us. The battle is to try and keep him beyond January. If he carries on the way he is then, being realistic, it will be difficult to do so. Whatever happens will happen-whether that is in January or the end of the season. I'm pretty sure he'll be going on to a higher level of football."
Amy income from a transfer fee will be a huge shot in the arm to Dulwich's cause. They released a statement earlier this month which claimed that Meadow Residential-the owners of their Champion Hill Stadium-have ended their "contractual obligations to pay players wages and oversee the clubs finances".
"We probably will be remunerated as club-in the short term and the long term," said Rose.
Ashley Carew scored twice with Rickie Hayles also on target as a late fightback secured Dulwich a 3-3 draw at Hendon on Tuesday, extending their unbeaten run to 12 league matches.
Striker Gavin Tomlin has broken his leg. Rose said: "It is a clean break, but we think his season may be over."
